The G.A.S Controller Replacement Probe Pack 25 is a temperature and humidity sensor designed for compatible Global Air Supplies environmental controllers that use the newer connector block attachment. Accurate climate monitoring is essential in hydroponics and indoor growing environments, where temperature and humidity directly influence plant health, nutrient uptake and overall yield inside a grow tent or grow room.
With a 10 metre sensor cable, this probe allows flexible placement within larger grow rooms, lung rooms or grow tents, ensuring the controller receives accurate environmental readings from the plant canopy area.
Key Benefits
• Replacement temperature and humidity probe for compatible G.A.S controllers
• 10 metre sensor cable for larger grow rooms or flexible placement
• Connector block attachment for newer controller models
• Restores accurate environmental monitoring
• Supports stable temperature and humidity control
• Suitable for hydroponics, coco and soil indoor growing setups
How It Solves Grow Problems
Environmental controllers rely on precise sensor data to regulate ventilation, humidity and temperature. If a probe becomes damaged or inaccurate, controllers may receive incorrect readings, causing unstable grow room conditions such as excess heat or humidity fluctuations.
Replacing the probe restores reliable environmental monitoring, allowing your controller to correctly regulate fans, humidifiers and dehumidifiers. Stable environmental conditions support healthy plant development, efficient nutrient uptake and improved plant performance during both vegetative growth and the flowering stage.
How to Use
-
Turn off and unplug the G.A.S controller before replacing the probe.
-
Remove the controller back cover to access the probe connection.
-
Locate the connector block attachment inside the unit.
-
Disconnect the existing probe from the connector block.
-
Plug the new Pack 25 probe into the connector block connection.
-
Replace the controller cover and secure it properly.
-
Position the probe at canopy height inside the grow tent or grow room for accurate temperature and humidity readings.
Before purchasing, remove the controller back cover to confirm which probe type your controller uses, as some older models use push-fit wire connections instead of the connector block system.
