The probe covers the full \u003cstrong\u003e0–14 pH range\u003c\/strong\u003e at \u003cstrong\u003e±0.02 pH accuracy\u003c\/strong\u003e with \u003cstrong\u003e0.01 pH resolution\u003c\/strong\u003e. A \u003cstrong\u003e10-foot cable\u003c\/strong\u003e runs from the sensor to the Batch TankLINK controller. The cable terminates on a \u003cstrong\u003eBNC connector\u003c\/strong\u003e that pushes onto the controller port. A quarter-turn clockwise locks it in place. Inside the typical hydroponic feed window of 5.5–6.5 pH, that accuracy is tight enough to confirm a fresh batch lands inside spec on the first mix.\u003c\/p\u003e\n\u003ch2\u003eCalibrating and Maintaining the TankLINK pH Probe\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eCalibration is a two-point process with \u003cstrong\u003epH 7.00\u003c\/strong\u003e and \u003cstrong\u003epH 4.01\u003c\/strong\u003e buffer solutions. 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","url":"https:\/\/growershouse.com\/products\/growlink-batch-tanklink-ph-sensor","provider":"GrowersHouse","version":"1.0","type":"link"}
