Restore accurate readings to your G.A.S controller
The Controller Replacement Probe (Pack 23) is a 10 metre push-fit temperature sensor for compatible G.A.S environmental controllers, replacing the older push-fit style probes fitted to earlier models. A faulty or drifting probe stops a controller reading temperature correctly, letting the room slip out of range and adding stress that slows growth and cuts yield. Fitting a fresh probe restores the accurate feedback the controller needs to regulate fans, heaters or cooling equipment, keeping conditions stable through vegetative growth and flowering.
Key Benefits
- Direct replacement temperature probe for compatible G.A.S controllers
- Older push-fit terminal fit for controllers made roughly a year or more ago
- 10 metre cable for flexible sensor placement in larger tents and rooms
- Restores accurate monitoring so climate equipment regulates correctly again
- Straightforward install using the existing push-fit terminal block
Is your controller reading the wrong temperature?
Environmental controllers rely on accurate temperature readings to run fans, heaters and cooling gear. When a probe is damaged or reading incorrectly, the room can suffer temperature spikes, humidity swings and plant stress. Swapping in a working probe returns reliable feedback so the system holds ideal conditions across hydro, coco and soil grows.
How to Use
- Turn off and unplug the controller before starting.
- Remove the back cover to access the probe connection.
- Confirm your controller uses the push-fit terminal style.
- Remove the old probe wires from the terminal block.
- Insert the new probe wires and secure them firmly.
- Route the 10 m cable into the grow space and position the sensor at canopy height.
- Reassemble the controller and power the system back on.
