Trusted by thousands of cultivators worldwide, GrowLink combines modular hardware with AI-driven analytics so you can automate dosing, dial in crop steering, and monitor every zone from a single dashboard. The complete GrowLink lineup is available at GrowersHouse — from the Core Controller and EC-6 Environment Controller to the Precision Irrigation Controller, terraLINK substrate sensors, Nutrient Dosers, and LINKS integration hubs — giving you the tools to scale rooms, cut labor, and protect every crop with data-backed decisions\u003cspan id=\"dots\"\u003e...\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv id=\"more\"\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\n\u003ch2\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0723\/9450\/6454\/files\/Growlink_Collection.webp?v=1778528600\" alt=\"Growlink Collection\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/h2\u003e\n\u003c\/div\u003e\n\u003ch2\u003eWhat GrowLink Controllers and Sensors Do for Growers\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eGrowLink products solve the biggest pain points in modern indoor growing: inconsistent climates, manual fertigation errors, and blind spots in the root zone. The GrowLink Core Controller and EC-6 manage HVAC, lighting, CO2, dehumidifiers, and fans across multiple rooms, while the Precision Irrigation Controller (PIC) automates shot timing and valve control for true 4-phase crop steering (P0–P3). terraLINK and terraLINK+ substrate sensors use TDR technology to report live VWC, EC, and root-zone temperature, feeding the Copilot AI engine that fine-tunes irrigation and nutrient recipes in real time. The result is tighter room-to-room consistency, lower water and nutrient waste, and higher-quality finished plants.\u003c\/p\u003e\n\u003ch2\u003eTypes of GrowLink Products Available\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eThe GrowLink ecosystem is fully modular. Environmental control runs on the Core Controller, EC-3\/EC-6, and All-In-One Connect Controller. Precision irrigation is powered by the PIC, and nutrient dosing is handled by the GrowLink Nutrient Doser, which supports up to 16-part blends including pH and additives. The terraLINK and ESM1 sensor families monitor substrate and environmental data, while the LINKS Hub and Integration Hub for TrolMaster allow you to connect existing equipment without ripping out your current setup. Everything ties together through Growlink OS — a cloud platform with mobile app, dashboards, alarms, scheduling, and open API support (BACnet, Modbus, SDI-12) for true scalability.\u003c\/p\u003e\n\u003ch2\u003eWhy Growers Choose GrowLink\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eGrowLink stands out because it is open, modular, and built around the way commercial growers actually work. Installation takes hours instead of weeks, hardware scales from a single room to multi-site operations, and the Copilot AI turns raw sensor data into actionable irrigation and fertigation decisions. Whether you are running a craft indoor room, a vertical farm, or a multi-zone greenhouse, GrowLink reduces labor hours, eliminates costly mixing mistakes, and delivers the consistency commercial markets demand.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003e\u003cstrong\u003eHow does a GrowLink system get set up in my grow room?\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp style=\"text-align: justify;\"\u003eA GrowLink build starts with a central controller — typically the Core Controller or EC-6 — connected to Wi-Fi and paired through the GrowLink mobile app. From there, you add LINKS devices, environment sensor modules, terraLINK substrate sensors, and irrigation or dosing hardware as needed. Because the platform is modular and uses long-range wireless or wired communication (up to ~500 ft), most rooms can be commissioned in a single afternoon and expanded later without rewiring.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eHow is GrowLink different from TrolMaster?\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp style=\"text-align: justify;\"\u003eTrolMaster is known for rock-solid local climate, lighting, and CO2 control, while GrowLink leads on analytics, AI-driven crop steering, and cloud workflows. The two are not mutually exclusive — GrowLink's Integration Hub for TrolMaster brings existing TrolMaster hardware into Growlink OS, so many facilities run both side by side and gain the strengths of each platform without replacing equipment.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eWhat is crop steering and how does GrowLink support it?\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp style=\"text-align: justify;\"\u003eCrop steering is a precision irrigation method that manipulates substrate VWC and EC across four phases (P0 ramp-up, P1 saturation, P2 maintenance, P3 dry-back) to push plants into vegetative or generative growth. GrowLink supports the full workflow with terraLINK substrate sensors for live root-zone data, the Precision Irrigation Controller for automated shot delivery, and the Copilot AI rules engine that adjusts timing and volume on the fly based on what your plants are actually doing.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eIs GrowLink worth it for a smaller operation?\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp style=\"text-align: justify;\"\u003eYes — while GrowLink is engineered for commercial scale, the modular LINKS line and entry-level controllers let smaller and scaling growers start with one or two rooms and add hardware as they grow. Users consistently report saved labor hours, better consistency between cycles, and the peace of mind that the same platform will still fit when they expand to additional zones or sites.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cbutton onclick=\"myFunction()\" id=\"myBtn\" class=\"readmore\"\u003eRead More\u003c\/button\u003e","products":[{"product_id":"growlink-4-channel-light-link","title":"Growlink 4-Channel Light LINK","description":"\u003ch2\u003e0-10V Analog Dimming Controller for Multi-Zone Grow Lighting\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eThe \u003cstrong\u003eGrowlink 4-Channel lightLINK\u003c\/strong\u003e drives up to \u003cstrong\u003e200 dimmable fixtures across four zones\u003c\/strong\u003e via four independent 0-10V analog outputs.

Place the unit close to the fixture array to keep 0-10V signal runs short. Analog dimming voltage drops over long wire runs and can cause uneven brightness across a row. Sunrise\/sunset ramping is the daily workhorse. Program a 10-30 minute ramp from 10% to 100% at lights-on and reverse it at lights-off to avoid light shock and stretch. Save recipes per crop cycle — veg ramps, flower DLI targets, finishing UV pulses — and reuse them across rooms running the same genetics. The trade-off is that channel-level control isn't fixture-level control. If two fixtures on the same channel need different intensities, split them onto separate channels rather than averaging.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e4× 0-10V Analog Outputs (50 Fixtures Each):\u003c\/strong\u003e Independent dimming across four zones with up to 200 fixtures total at industry-standard 0-10V signaling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGavita, Fluence, TrolMaster Compatible:\u003c\/strong\u003e Plugs into most 0-10V dim ports on commercial LED drivers and ballasts without protocol adapters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSunrise\/Sunset Ramping in Growlink OS:\u003c\/strong\u003e Build per-zone ramp profiles, save recipes by crop cycle, and reuse them across rooms running the same genetics.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowlink HUB Required, 24VDC Input:\u003c\/strong\u003e Powers from the HUB over RJ-45 and pulls 12W max at full load with 125mA per dim channel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDIN Rail Mounting:\u003c\/strong\u003e Mounts flush in a control panel and keeps signal wiring tidy across a multi-zone lighting build.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003ctable style=\"width: 100%;

Place the controller centrally enough that valve runs stay under the FET's 1A current limit per channel. 24V latching solenoids draw more on the pull pulse, so size cable gauge and split high-draw valves across channels. For larger facilities, scale by adding additional valveLINK units to the same Growlink OS account. Channels stay logically grouped under zone names rather than module IDs. Sensor-based mode pairs well with substrate moisture probes. The controller delays the next shot until water content drops past the dryback target, which is core to crop steering.

In rockwool blocks and slabs, slide the rod in 1 inch from the bottom, equidistant between two plants. In 1-gallon coco pots aim for 2 inches up from the bottom. In 2-gallon and larger, 3 inches. If the 30 ft factory cable doesn't reach, splice with 18 AWG 3-conductor cable for the extension. Keep the total run under 175 ft from probe to controller.

Growers running multiple HUBs across rooms often keep a spare on the shelf so a dead brick doesn't pull a controller offline mid-run.

The \u003cstrong\u003evalveLINK pulls 2.7A\u003c\/strong\u003e, and the \u003cstrong\u003erelayLINK pulls 1.5A\u003c\/strong\u003e. Neither lands inside this 24VDC power adapter's 1A budget. Those need the 3A LINK Power Supply instead. Match the Growlink LINK PSU current to the device, and the system stays stable through transient loads on every output the module drives. Keep one labeled by room so a swap during a service window takes seconds. The unit's compact size fits inside most controller boxes without dedicated mounting space.

The TankLINK LCD wizard walks the probe through each buffer in turn and locks the cal at a stable voltage. Run cal at the start of each batch or whenever the reading drifts past ±0.05 pH between known mixes. The pH probe ships in a storage cap of pH 4 buffer and potassium chloride. The membrane needs to stay wet between runs. A dry membrane is the fastest way to kill a pH probe early. Keep the storage cap on whenever the sensor sits out of solution. Position this TankLINK pH probe near the recirculation return so the read reflects what the canopy actually drinks. Plug-and-play wiring keeps a single-probe swap during teardown under a minute. The nutrient tank pH probe twists out of the BNC port and a fresh one twists in.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e0–14 pH Range:\u003c\/strong\u003e Full-scale read covers anything a hydro feed will ever hit, including post-dosing spikes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e±0.02 pH Accuracy:\u003c\/strong\u003e Tight enough to confirm fresh mixes land in the 5.5–6.5 feed window on the first measurement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e0.01 pH Resolution:\u003c\/strong\u003e Catches small drifts between feeds before they show up as canopy stress symptoms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBNC Connector with 1\/4-Turn Lock:\u003c\/strong\u003e Push-on, twist-lock fit on the TankLINK controller's labeled port — no rewiring at swap.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo-Point Calibration:\u003c\/strong\u003e pH 7.00 and pH 4.01 buffers through the LCD wizard handle the full cal in one pass.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #333; color: #fff;\"\u003e\n\u003cth style=\"padding: 8px; text-align: left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding: 8px; text-align: left;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003epH Range\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e0–14\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eAccuracy\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e±0.02 pH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eResolution\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e0.01 pH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eConnector\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eBNC (push + 1\/4-turn CW lock)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eCable Length\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e10 ft (3 m)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eCalibration\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eTwo-point @ pH 7.00 and pH 4.01 via LCD wizard\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eStorage\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eStorage cap with pH 4 buffer + potassium chloride\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eCompatible Controller\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eGrowlink Batch TankLINK\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Growlink","offers":[{"title":"Default Title","offer_id":48240874619094,"sku":"GL-LINK-PHSENSOR","price":79.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0723\/9450\/6454\/files\/Growlink_Batch_TankLINK_pH_Sensor_main_image.webp?v=1778627423"},{"product_id":"growlink-level-sensor-for-batch-tanklink","title":"Growlink Level Sensor (for Batch TankLINK)","description":"\u003ch2\u003eReading Tank Level with the Growlink Batch TankLINK Level Sensor\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eThe \u003cstrong\u003eGrowlink Batch TankLINK Level Sensor\u003c\/strong\u003e floats a \u003cstrong\u003eserpentine pontoon\u003c\/strong\u003e directly in the nutrient tank.

The nutrient tank level sensor wires in with no protocol conversion. Plug-and-play installation keeps a sensor swap to a few minutes during tank teardown. Lift the pontoon, unplug the Molex, drop in the new unit, and the controller picks the reading back up at the next sample cycle. Tank cleaning between runs is the most common time to inspect the pontoon for scale buildup. A wipe with a soft cloth keeps the batch tank level sensor reading honest across the next harvest cycle. The continuous 4–20mA reading also pairs with the controller's logged history for season-over-season fill-rate analysis.

The plug-and-play fit means a damaged ClimaLINK TerraLINK extension cable swaps out in under a minute. Twist the collar loose, pull the cable, replace, and twist tight.

That keeps the data signal clean over the 10m run without the resistance noise that creeps into improvised splice lines. Pair this length with the 5m option if a room mixes short canopy drops with longer bench-to-wall runs. Smaller flowering rooms often work the other way around.

The kit branches one canopyLINK HUB port across multiple ClimaLINK or TerraLINK sensors. The 4-pin M8 connectors at every junction stay sealed against grow-room humidity and the daily dust that kills generic patch cables. The T-connector lets one HUB port feed two sensor branches at the same time. The end cap closes off any unused branch leg to keep the bus terminated cleanly.

This frees up the remaining canopyLINK ports for additional zones. Place the T-connector near the canopy so each branch can route to its sensor location without strain. Daisy-chaining beyond a single split risks signal weakening on long cable runs. For more than two sensors per branch, drop in an additional HUB or canopyLINK module rather than stacking extra T-connectors. The end cap matters more than it looks: an open branch leg can collect moisture and corrode the contacts over a flowering cycle. Cap the unused side at install and the assembly stays sealed for the life of the run. The trade-off is that every M8 mating point is one more thing to inspect.

Most rooms work through two filters a year on back-to-back harvest cycles.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eCalibrated Airflow Match:\u003c\/strong\u003e Filter resistance is set to the same profile used during ClimaLink factory calibration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo Filters Per Pack:\u003c\/strong\u003e Enough for one full sensor swap and a spare, or two ClimaLink units in the same room.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtects ±0.18°F Accuracy:\u003c\/strong\u003e Keeps the aspirated airflow rate stable so temperature, humidity, and VPD readings stay on spec.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHarvest-Cycle Swap:\u003c\/strong\u003e Standard maintenance cadence — replace at the end of each run, not on a quarterly clock.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool-Free Replacement:\u003c\/strong\u003e Filter housing pops open by hand; the element drops in and snaps closed in under a minute.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #333; color: #fff;\"\u003e\n\u003cth style=\"padding: 8px; text-align: left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding: 8px; text-align: left;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003ePack Quantity\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e2 filters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eCompatible Sensor\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eGrowlink ClimaLink (aspirated climate sensor)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eCalibration Match\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eFactory-calibrated airflow profile\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eReplacement Interval\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eEvery harvest\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eProtects Accuracy Of\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eTemperature ±0.18°F (±0.1°C), Humidity ±1% RH, VPD, optional CO2 ±3%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eInstallation\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eTool-free, snap-fit housing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Growlink","offers":[{"title":"Default Title","offer_id":48240876159190,"sku":"CLIMALINK-FIL","price":9.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0723\/9450\/6454\/files\/Growlink_Climalink_Replacement_Filters_main_image.webp?v=1778625015"},{"product_id":"growlink-batch-tanklink","title":"Growlink Batch TankLINK","description":"\u003ch2\u003eGrowlink batch tankLINK Controller for Real-Time Tank and Nutrient Management\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eThe \u003cstrong\u003eGrowlink batch tankLINK Controller\u003c\/strong\u003e handles pH, EC, temperature, and tank-level monitoring through a single \u003cstrong\u003e24VDC\u003c\/strong\u003e unit pulling roughly \u003cstrong\u003e5W\u003c\/strong\u003e at full duty.

Drop it into a tank for submerged reads. The in-line option uses an FC50P or FC75P gland and nut fitting through a tee, sized for ½″ and ¾″ NPT pipes. The lab cable variant talks to the Sensorex CM1000 meter. The 10ft and 30ft process cables wire into Sensorex CX-series transmitters such as the CX105, CX2000, CX2000RS, and CX3100. Pick the cable length that matches the run from probe to transmitter. Clean the graphite surface with gentle detergent or 5% HCl in a small cup between batches. The Sensorex CS150 conductivity sensor holds calibration through the cleaning cycle. Most rooms work through two probes a season once a graphite element has logged enough hours in high-EC drainback. Pair this graphite EC\/TDS sensor with a Sensorex transmitter for continuous logging through the run. Keep a spare on the shelf for swap-day during summer drainback peaks. A spare cuts downtime when a probe needs cleaning mid-bloom.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003e12 mm Graphite Contacting Probe:\u003c\/strong\u003e Cost-effective EC\/TDS read for lab and light-industrial reservoir or in-line use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eK=1.0 Cell Constant:\u003c\/strong\u003e Sized for the standard hydroponic feed range — good resolution from veg through bloom EC values.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePT1000 Temperature Element:\u003c\/strong\u003e Automatic Temperature Compensation built into the cable keeps EC readings honest across tank temp swings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBNC + Tinned Lead Terminations:\u003c\/strong\u003e BNC plugs into instrumentation; tinned leads land on Sensorex CX-series transmitter terminals.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTank or In-Line Mounting:\u003c\/strong\u003e Submerge in the reservoir or install in a tee with FC50P (½″ NPT) or FC75P (¾″ NPT) gland fittings.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #333; color: #fff;\"\u003e\n\u003cth style=\"padding: 8px; text-align: left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding: 8px; text-align: left;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eSensor Type\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eContacting conductivity \/ TDS, graphite electrodes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eProbe Diameter\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e12 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eCell Constant\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eK = 1.0 \/ cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eTemperature Element\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003ePT1000 (Automatic Temperature Compensation)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eConnector \/ Termination\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eBNC + tinned leads (TL)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eCable Length Options\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e10 ft (3 m) or 30 ft (9 m)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eBody Material\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003ePlastic body, graphite measuring surfaces\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eOperating Range\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003e0–70 °C (32–158 °F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eMounting\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eSubmersible in tank, or in-line via FC50P (½″ NPT) \/ FC75P (¾″ NPT)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eCompatible Transmitters\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eSensorex CX105, CX2000, CX2000RS, CX3100 (process cable); CM1000 (lab cable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #fff;\"\u003e\n\u003ctd style=\"padding: 8px;\"\u003eCleaning\u003c\/td\u003e\n\u003ctd style=\"padding: 8px;\"\u003eGentle detergent or 5% HCl in cup\/beaker\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Growlink","offers":[{"title":"10' Cable","offer_id":48240876945622,"sku":"CS150TC-K-1.0-P1K-10-BNC-TL","price":199.0,"currency_code":"USD","in_stock":true},{"title":"30' Cable","offer_id":48240876978390,"sku":"CS150-K-1.0-P1K-30-BNC-TL","price":249.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0723\/9450\/6454\/files\/Sensorex_TDS_Sensor_main_image.webp?v=1778634491"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0723\/9450\/6454\/collections\/Growlink_logo.jpg?v=1778527266","url":"https:\/\/growershouse.com\/collections\/growlink.oembed?page=3","provider":"GrowersHouse","version":"1.0","type":"link"}
