Conductivity, volumetric moisture content and temperature. It does not read pH, and no amount of looking will find a pH mode on it. The ranges are specific. Temperature covers 5 to 40 degrees Celsius, which is 40 to 104 Fahrenheit, to within one degree. Conductivity runs 0 to 15, accurate to 0.2 across the lower half and to 8% above a reading of five. Moisture covers 5% to 70% in mixed media and coir, to within 5%. The probes are stainless steel, long format, and measure 8 in or 200 mm. One AA battery runs it. Readings pass over Bluetooth to the Pulse app, which runs on iOS and Android in five languages. Data exports from the app for review across a cycle. The single most useful operational fact is what the meter does not need. There is no calibration, no calibration solution and no thirty day reminder to ignore.

The meter does not work in media with large voids, which rules out perlite. It also does not work in media that can be permanently distorted, which rules out rockwool. The reason sits in how the reading is taken. Two probes measure the material between them, so an air void reads as dry substrate. A slab that deforms around a spear never springs back to its original density. That means the second reading is of the channel you made, not the slab. That leaves a wide field where it does work: soil, coco coir, potting mix, other mixed media and nutrient solution itself. Pot size matters here as well. Bluelab set a minimum of two litres, or half a gallon, since probes in a small pot read the container as much as the medium. For a grower on slabs the honest answer is a different tool. Runoff conductivity, or a sensor built to live inside a slab, will tell you more than a handheld spear ever can.\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\u003eThree readings in one push:\u003c\/strong\u003e Volumetric moisture, conductivity and temperature from the root zone.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo calibration at all:\u003c\/strong\u003e No solutions and no reminder, unlike every pH meter in the range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMoisture 5% to 70%:\u003c\/strong\u003e In mixed media and coir, accurate to within five percent.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductivity 0 to 15:\u003c\/strong\u003e Accurate to 0.2 below a reading of five, and to 8% above it.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e8 in stainless probes:\u003c\/strong\u003e Long format, 200 mm, pushed straight into the substrate.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBluetooth to the Pulse app:\u003c\/strong\u003e On iOS and Android, with data export across a growing cycle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNot for rockwool or perlite:\u003c\/strong\u003e Bluelab rule out voided and permanently deformable media.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo litre minimum pot:\u003c\/strong\u003e Below half a gallon the probes read the container, not the medium.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%;

monitor\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eThe HI981420 is a wall-mounted monitor that sits beside the reservoir and reads three parameters continuously from one probe. That probe is the HI1285-8: a pH electrode with a renewable cloth junction, an amperometric EC\/TDS sensor and an internal temperature sensor. All three sit in one polypropylene body on a 2 m cable. Ranges run 0.00 to 14.00 pH, 0.00 to 10.00 mS\/cm, and 0 to 5000 ppm on the 0.5 conversion factor. Accuracy holds at ±0.05 pH and ±0.1 mS\/cm across the lower half of the conductivity scale, where most recirculating feeds live. Temperature covers 32.0 to 140.0 °F and compensates every reading, so a cold reservoir in the morning does not read as a weak feed. The enclosure is rated IP65. Nutrient mist and splash reach everything eventually, and a sealed face keeps a meter on the wall instead of in a drawer.\u003c\/p\u003e\n\u003ch2\u003eHydroponic nutrient monitoring that catches drift between hand checks\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eProbe placement decides whether the number on the screen matches the tank. Submerse the probe tip at least an inch and a half into moving solution. A return-line outlet or the draw side of a pump reads true; a dead corner of the tank lags by hours. Logging runs on its own every fifteen minutes and holds the last thirty days, keeping minimum, maximum and average values for each parameter. That history is where a pattern shows up instead of a surprise. You see the pH climb that starts two days after a res change, or the conductivity creep that only appears during lights-out. High and low alarms flash the display and trip an LED when a parameter leaves the band you set for it. One Quick Cal sachet calibrates pH and conductivity together, which is the practical difference between recalibrating on schedule and putting it off. This unit monitors and does not dose; it reports what the solution is doing and leaves the correction to you. The probe supplied with it is the unthreaded submersion type, so plumbing a sensor into a line calls for the threaded inline model instead. Keep the protective cap on the pH bulb whenever the probe is out of solution for more than a few minutes. A dried-out bulb is the commonest way one of these ends up reading slow.\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\u003e3-in-1 HI1285-8 probe:\u003c\/strong\u003e A pH electrode, an amperometric EC\/TDS sensor and an internal temperature sensor share one body, so one port covers continuous pH and EC monitoring.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuick Cal single-solution calibration:\u003c\/strong\u003e One HI50036 sachet calibrates pH and conductivity together, which cuts the weekly routine down to a couple of minutes.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e30-day automatic datalog:\u003c\/strong\u003e Records every 15 minutes and stores minimum, maximum and average values for each parameter.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh and low alarms:\u003c\/strong\u003e A flashing display and an LED mark the moment a parameter leaves the range you set.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIP65-rated enclosure:\u003c\/strong\u003e Sealed against the mist and splash that come with a working nutrient room.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSelectable TDS factor:\u003c\/strong\u003e Switch between 0.5 and 0.7 so the ppm figure on screen matches the scale your feed chart uses.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUSB-C data transfer:\u003c\/strong\u003e Pull the log straight onto a memory stick or a PC without proprietary software.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmbient light sensor:\u003c\/strong\u003e Dims the green-backlit LCD so a bright readout is not fighting a dark-period room.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%;

The meter is rated at \u003cstrong\u003e±2%\u003c\/strong\u003e accuracy across its range. A built-in thermometer reads water temperature from 0 to 80°C in 0.1° steps. \u003cstrong\u003eAutomatic temperature compensation\u003c\/strong\u003e covers 1 to 50°C, so readings stay consistent as solution temperature shifts.

If it drifts, it can be recalibrated with a small screwdriver against a matching NaCl solution. A hold button freezes the reading so you can lift the probe and record it. To save batteries, the meter shuts itself off after 10 minutes without use. Two LR44 button cells come installed and last around 1,000 hours.

Read the source first, since tap water alone can carry a few hundred ppm before any nutrients go in. Mix the batch, stir well, then take the reading once the solution has settled. Dip the probe to the immersion line and swirl gently to clear bubbles off the electrodes. Wait for the display to stop moving, press hold, and lift the meter out to read it. Rinse the probe in clean water after every test so salts don't build up. Remember that the meter reads on a 0.5 scale. Feed charts written on a 0.7 scale will show higher numbers for the same solution, so convert before comparing. HM Digital suggests calibrating near the upper third of the range you test most. For a reservoir run around 800 to 1,200 ppm, a mid-range NaCl standard keeps readings honest. Recheck calibration every few months and whenever readings stop matching your feed chart. Store the meter in its case with the cap on.\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\u003e0-9990 ppm Range:\u003c\/strong\u003e Covers RO water, tap water and full-strength nutrient solution.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e±2% Accuracy:\u003c\/strong\u003e With 1 ppm resolution up to 999 ppm and 10 ppm steps above.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-In Thermometer:\u003c\/strong\u003e Reads 0 to 80°C, with automatic temperature compensation from 1 to 50°C.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHold Function:\u003c\/strong\u003e Freezes the reading so it can be recorded after the probe is lifted.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFactory Calibrated:\u003c\/strong\u003e Set at 342 ppm NaCl and adjustable with a mini screwdriver.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuto-Off and Long Battery Life:\u003c\/strong\u003e Shuts off after 10 minutes idle;

Thirty water detectors, eight water content sensors, and exactly one sensor board. One conductivity and temperature probe, and one pH probe, and no more of either.

A room with five benches and three valves each is already at fifteen, and that is one room. Each output holds its own schedule, which is what makes bench level zoning worth the wiring. There are two scheduling modes and neither gets much attention. One is a recycling timer, running a set duration at a set interval through the day. The other is time of day scheduling, where each event is pinned to a clock time with its own duration. Recycling suits rockwool and small containers, while clock events suit a crop being pulsed around a lighting schedule. Data logging runs underneath both, so a dry back can be traced afterwards rather than argued about. The app sends alerts, which on an irrigation system matters more than remote control does.

Conductivity shows as EC from \u003cstrong\u003e0.0 to 9.9\u003c\/strong\u003e, or as CF, ppm 500 (TDS) or ppm 700, whichever scale your feed chart uses. Temperature covers \u003cstrong\u003e32 to 122°F\u003c\/strong\u003e (0 to 50°C) at ±2°F, displayed in Fahrenheit or Celsius. Automatic temperature compensation keeps the conductivity readings honest as solution temperature drifts. The backlit screen stays readable under a dim canopy or in a dark reservoir room. It runs on two AAA batteries and switches off after four minutes idle. The box includes pH 7.0 and pH 4.0 calibration sachets, a KCl storage sachet and a dibber for opening a hole in firm media.\u003c\/p\u003e\n\u003ch2\u003eUsing the Leap pH Probe in Soil, Coco and Runoff\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eThe Leap pH probe is what sets this kit apart from a reservoir-only meter. Use the dibber to open a hole in moist soil or coco, then slide the probe in. It reads pH where the roots are feeding, not just in the runoff. Coco growers often check the slab, the drip and the runoff in one pass and compare all three. That pattern shows salt buildup or a drifting pH well before leaves start to complain. In a hydro system the same probes drop straight into the reservoir or a sample cup. Calibrate the pH side with the two included sachets before first use, then again on a regular schedule. Keep the probe tip wet in KCl storage solution between sessions so it stays responsive. The conductivity probe needs no calibration at all, which saves time on a busy feed day. The honest limit is probe life. The meter carries a five-year warranty, while the Leap probe is covered for six months as a wear item. Plan on replacing the pH probe periodically, especially with daily use in dense media.\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\u003eThree Readings in One:\u003c\/strong\u003e pH, conductivity and temperature come from one handheld unit, so a full check takes a single pass.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeap pH Probe:\u003c\/strong\u003e A toughened tip pushes into soil and coco for direct root-zone pH readings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCalibration-Free Conductivity Probe:\u003c\/strong\u003e The spear-tip EC probe goes straight into media or solution with no calibration routine.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable Units:\u003c\/strong\u003e Switch between EC, CF, ppm 500 and ppm 700 to match any nutrient chart.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic Temperature Compensation:\u003c\/strong\u003e Conductivity stays accurate as solution or media temperature changes through the day.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLong Probe Cables:\u003c\/strong\u003e 2 m leads reach the back of a bench or the bottom of a deep reservoir.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFive-Year Meter Warranty:\u003c\/strong\u003e The meter body carries a five-year limited warranty.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0723\/9450\/6454\/files\/bluelab-combo-plus-meter-probe-included.png\" alt=\"Bluelab Combo Meter Plus with Leap pH Probe\" title=\"Bluelab Combo Meter Plus with Leap pH Probe\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0723\/9450\/6454\/files\/bluelab-combo-plus-meter-probe-included-probe-coco.png\" alt=\"Bluelab Leap pH Probe in coco\" title=\"Bluelab Leap pH Probe in coco\"\u003e\u003c\/div\u003e\n\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable style=\"width:100%;

Stirring the reservoir with the stem speeds that up and mixes the nutrients at the same time. Lift it out, dip it back in, and read the value where the lights flash. When the lights dance between two marks, the true reading sits halfway between them. Check the fresh mix, then check runoff, and the difference tells you whether salts are building in the media. The probe needs cleaning every two weeks with a plain, unscented cream cleanser and a chamois. Scented or abrasive cleaners damage the probe face and throw readings off. Use alkaline cells only, because rechargeable batteries are not suited to the meter.

One pump carries pH adjuster and the other two carry nutrient stock solution. That rate is the number that matters most here, because the same pod also comes with slower pumps fitted. The M3 runs at 120 ml per minute, a tenth of the flow, across the same three pump layout. So the real choice between the two is reservoir volume rather than features. A large tank that needs a correction applied quickly wants the faster pumps. A small one does not, and overshooting a target is easier with them. The unit is wall mounted through holes at the top and the bottom of the case. It measures 392 mm across, which is 15.4 in, by 154 mm or 6 in high, and 112 mm or 4.4 in deep. Power arrives through an external supply taking 100 to 240 V at 50 or 60 Hz and delivering 24 V DC to the pod. The operating range is 5 to 40 degrees Celsius, or 41 to 104 Fahrenheit.

The older Pro Controller, part CONTPRO, is no longer available, and the current partner is the Pro Controller Wi-Fi, part BCTPRC02. Pods can be linked for more complex schedules, up to a ceiling of twelve pumps. An L3 cannot be linked to an M3 or an M4, though. The pod comes with one 13 ft run of acid and alkaline resistant tubing plus three 13 ft runs of food grade tubing. Peristaltic tubing is a wear part with a life beyond 750 hours of pump running time.

During each dose, the pod switches pumps on and off so every part lands in its correct proportion. Mount the pod higher than both the reservoir and the stock bottles, but never directly above the tank. Keep it within about five feet of an outlet and close enough for the outlet tubes to reach. Cut every tube at a 45-degree angle so the inlet never seals against the bottom of a bottle. The outlet tubes should drip above the waterline, kept apart so concentrated parts do not precipitate together. Prime each pump by hand before the first automatic dose. Calibrate the nutrient pumps at setup, after any nutrient change and every 30 days. Accurate ratios need about 100 seconds of total dosing time. For tanks under roughly 25 gallons, dilute every nutrient part with an equal volume of water. The peristaltic tubing is a wear part rated for more than 750 running hours, and replacements swap in quickly.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h3\u003e\u003cul style=\"text-align: justify;\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree Peristaltic Pumps:\u003c\/strong\u003e Each pump doses up to 120 ml per minute, and any of them can be set for pH or nutrient.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePro Controller Driven:\u003c\/strong\u003e The Pro Controller Wi-Fi reads the tank and sends the dosing triggers, so the pod needs no sensors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeed Chart Ratios:\u003c\/strong\u003e The Edenic app turns ml-per-gallon entries into pump ratios for two-part and multi-part nutrient lines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndividual Pump Calibration:\u003c\/strong\u003e Each nutrient pump calibrates to its own solution, which keeps viscous parts in proportion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChains to 12 Pumps:\u003c\/strong\u003e Up to three M-series pods link to one controller for complex multi-part schedules.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChemical-Resistant Tubing:\u003c\/strong\u003e PTFE pH tubing handles undiluted Bluelab pH Up and pH Down, and opaque tubing helps limit algae.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaceable Wear Parts:\u003c\/strong\u003e Pump motors, cassettes and tubing swap out individually instead of replacing the whole pod.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp style=\"text-align: justify;\"\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\u003ctable style=\"width:100%;
