Controller Replacement Probe - (Pack 25) 10m length with Connector Block

Restore accurate readings to your G.A.S environmental controller

The G.A.S Controller Replacement Probe (Pack 25) is a temperature and humidity sensor for compatible Global Air Supplies environmental controllers that use the newer connector block attachment. Accurate climate data is essential indoors, where temperature and humidity directly affect plant health, nutrient uptake and yield. With a 10 metre sensor cable, the probe can be positioned at canopy height even in larger grow rooms, lung rooms or tents, giving the controller the accurate readings it needs to regulate fans, humidifiers and dehumidifiers correctly.

Key Benefits

• Replacement temperature and humidity probe for compatible G.A.S controllers
• 10 metre sensor cable for flexible placement in larger spaces
• Connector block attachment for newer controller models
• Restores accurate monitoring after a probe fails or drifts
• Supports stable temperature and humidity control across hydro, coco and soil setups

Unreliable readings throwing your grow room climate off?

Environmental controllers rely on precise sensor data to regulate ventilation, humidity and temperature. A damaged or inaccurate probe feeds the controller bad data, causing excess heat, humidity swings and fans running at the wrong speed. Fitting a fresh probe restores reliable monitoring at canopy height so the controller can hold a stable climate through both vegetative and flowering stages.

How to Use

1. Turn off and unplug the G.A.S controller before replacing the probe
2. Remove the controller back cover to access the probe connection
3. Locate the connector block attachment inside the unit and disconnect the old probe
4. Plug the new Pack 25 probe into the connector block
5. Replace the cover and secure it properly
6. Position the probe at canopy height for accurate temperature and humidity readings

Before ordering, remove the controller back cover to confirm it uses the connector block system rather than older push-fit wire connections.
