The G.A.S Controller Replacement Probe Pack 22 is a temperature and humidity sensor designed to replace worn or faulty probes used with compatible G.A.S environmental controllers. Accurate environmental monitoring is essential in hydroponics and indoor growing, as even small fluctuations in temperature or humidity inside a grow tent or grow room can affect plant health and development. This replacement probe features a push fit terminal connection and a 5 metre sensor cable, making it suitable for older G.A.S controllers that use exposed wire style connectors. Once installed, the probe allows the controller to accurately measure environmental conditions so ventilation and climate equipment can respond correctly. Key Benefits • Replacement temperature and humidity probe for G.A.S controllers• 5 metre sensor cable for flexible positioning within grow rooms• Push fit terminal connection for compatible older controllers• Restores accurate environmental monitoring• Helps maintain stable grow room climate control• Suitable for hydroponics, coco and soil indoor growing setups How It Solves Grow Problems Environmental controllers rely on accurate sensor readings to regulate ventilation, humidity and temperature. If a sensor becomes damaged or inaccurate, growers may experience incorrect climate control, leading to unstable humidity levels, excess heat, or poor airflow inside the grow room. Replacing the probe restores accurate environmental monitoring so controllers can properly manage fans, humidifiers, and other climate equipment. Stable temperature and humidity levels help maintain healthy plant growth, support strong root development, improve nutrient uptake, and create optimal conditions during both vegetative growth and the flowering stage. How to Use Turn off and unplug the G.A.S controller before installation. Remove the back cover of the controller to access the probe connection terminals. Disconnect the existing sensor wires from the push fit terminal block. Insert the new probe wires into the terminal block according to the controller wiring layout. Secure the connections and replace the controller back cover. Position the probe at canopy height inside the grow tent or grow room for accurate readings. Power the controller back on and confirm temperature and humidity readings are displayed correctly. Before purchasing, check your controller connection type to ensure you select the correct replacement probe for your system.
