Replacement temp probe for the Growlink batch tankLINK — continuous solution monitoring, plug-and-play fit.
The Growlink batch tankLINK Temp Sensor is the purpose-built replacement temperature probe for the batch tankLINK controller. It delivers continuous, real-time nutrient solution temperature readings directly into Growlink OS, keeping your fertigation data complete and your automation logic intact.
The Growlink batch tankLINK Temp Sensor (SKU: GL-LINK-TEMPSENSOR) is the OEM-matched temperature probe for the batch tankLINK nutrient tank monitoring controller. It connects directly to the batch tankLINK's terminal block input and feeds live solution temperature data into the Growlink LINKS ecosystem and Growlink OS dashboard.
Solution temperature is not a secondary metric. It directly affects nutrient solubility, uptake kinetics, dissolved oxygen levels, and microbial activity in your reservoir. Having an accurate, continuously logged temperature reading in the same interface where you monitor EC, pH, and tank level means deviations trigger alerts before they stress the crop — not after you notice something wrong in the room.
This is a replacement or spare-probe purchase — not a standalone monitoring solution. It is the right buy if you are already running a Growlink batch tankLINK controller and need to replace a worn or damaged temperature probe, add a second probe to a multi-tank setup, or keep a spare on-hand to eliminate downtime when a probe fails mid-cycle.
Commercial cannabis and hemp operators running the Growlink LINKS platform — whether a single batch tank in a boutique room or multiple tanks across a scaled facility — depend on all four sensor inputs (EC, pH, temperature, level) being live and accurate at all times. A missing or faulty temp probe creates a blind spot in your automation logic and breaks the alert chain in Growlink OS.
Plug-and-play fit: The probe is designed for direct connection to the batch tankLINK controller's terminal block — no re-wiring, no configuration changes. Replace the probe, re-seat the connection, and your temperature channel is back online.
Accuracy and resolution: The sensor delivers ±2°C (±3.6°F) accuracy with a resolution of 0.02°F — sufficient for tracking solution temperature drift in commercial fertigation conditions and for triggering the high/low threshold alerts configurable on the batch tankLINK controller.
Built for the grow environment: The probe is constructed for continuous submersion in nutrient solution in high-humidity, demanding cultivation environments — the same standard as the rest of the Growlink LINKS accessory line.
The batch tankLINK controller accepts inputs for EC, pH, temperature, and tank level. All four channels feed into the Growlink HUB and surface in Growlink OS for centralized monitoring, real-time alerts, and historical data logging — the controller stores up to 21,600 data points per sensor with graphical history on its onboard LCD.
Growlink OS connects batch tankLINK data into the wider LINKS automation network alongside your valveLINK irrigation channels, climaLINK environmental sensors, and canopyLINK substrate readings. Keeping your temperature probe in spec means your tank management data is complete, your alert thresholds are meaningful, and your Growlink Copilot automation has the full picture it needs to act. A Growlink HUB is required to connect the batch tankLINK to Growlink OS — confirm your infrastructure before ordering additional probes.

This is the standalone replacement temperature probe sold separately. The batch tankLINK controller ships with a temperature probe included. Order the GL-LINK-TEMPSENSOR when you need a replacement, a spare, or an additional probe for a second tank on the same controller.
Yes. The temperature probe connects to the batch tankLINK controller, which in turn requires a Growlink HUB to communicate with Growlink OS. The probe itself is passive — it does not connect independently to the HUB or any other LINKS device.
The GL-LINK-TEMPSENSOR is matched to the batch tankLINK controller's terminal block input. Growlink's other LINKS modules use different sensor types and connection standards. Contact us to confirm compatibility before ordering if you have a non-tankLINK application.
The batch tankLINK controller lets you set high and low alarm thresholds for each sensor input, including temperature. When solution temp drifts outside your configured range, the controller triggers on-screen alerts and — when connected via HUB to Growlink OS — push notifications through the Growlink mobile app. Temperature data is also logged continuously, with up to 21,600 data points per sensor stored on the controller's onboard memory.
