Quick Release Controller Replacement Probe (Pack 31)

The Quick Release Controller Replacement Probe (Pack 31) is a genuine temperature sensor designed for use with G.A.S Enviro4, Enviro V2, and Intelligent Humidity Controller (IHC Dual) units. Accurate temperature monitoring is essential in hydroponics and indoor growing environments, where stable climate control directly impacts plant health, nutrient uptake and overall yield.

This probe features a plug-and-play quick release connection, making replacement simple without needing to modify controller settings or firmware. With a 5 metre sensor cable, growers can position the probe exactly where accurate readings are needed within a grow tent or grow room.

Once installed, the probe allows the controller to monitor ambient temperatures and automatically adjust ventilation systems to maintain ideal conditions throughout vegetative growth and the flowering stage.

Key Benefits

• Genuine replacement temperature probe for G.A.S controllers
• Compatible with Enviro4, Enviro V2 and IHC Dual controllers
• 5 metre cable for flexible grow room placement
• Quick-release plug-and-play installation
• Accurate temperature monitoring for climate automation
• Supports stable ventilation and environmental control
• Ideal for hydroponics, coco and soil indoor growing setups

How It Solves Grow Problems

Environmental controllers rely on accurate temperature readings to regulate ventilation systems. If a sensor becomes damaged or inaccurate, grow room conditions can drift outside optimal ranges, leading to heat build-up, slowed vegetative growth, or plant stress during flowering.

Replacing the probe restores reliable temperature monitoring so controllers can properly adjust fan speeds and maintain stable environmental conditions. Consistent temperatures improve plant health, support efficient nutrient uptake, and help maintain the optimal climate needed for strong growth and improved yields.

How to Use

1. Turn off and unplug your Enviro controller or IHC Dual controller.

2. Disconnect the existing temperature probe from the controller’s sensor port.

3. Plug the Pack 31 quick-release probe into the controller port.

4. Route the 5m cable neatly along tent poles or grow room walls, avoiding tight bends or pinch points.

5. Position the probe at canopy height, away from direct light, heaters or strong airflow.

6. Power the controller back on and confirm temperature readings are displayed correctly before resuming automatic control.
