Description
The probe that keeps reading in a wet room
The G.A.S High Humidity Replacement Sensor is the GSE probe built for rooms that sit at 80%+ RH, where an ordinary sensor saturates and stops telling the truth. G.A.S took it from the mushroom growing industry, where sustained high humidity is the normal working condition, and adapted it for their own controllers. A PTFE covering keeps liquid off the element, so the probe carries on reading where a standard one would drift or fail outright.
Key Benefits
- Built for sustained high humidity, not merely rated to survive it
- Withstands partial or total submersion — dry it out and it reads accurately again
- PTFE protective covering stops liquid saturation and mechanical failure
- Genuine GSE sensor rather than a generic substitute
- Two fittings available so it matches the controller you already own
Which fitting do I need?
- Enviro & IHC. For G.A.S environmental controllers and the Intelligent Humidity Controller
- AC-EC. For the AC-EC controller, which drives your extraction whatever the fan's power type
Standard probes dying in your room?
A probe sited near a humidifier, caught by foliar spraying, or simply living in a room that never drops below 80% will take on moisture, and once the element is saturated the controller is acting on numbers that are no longer real. That shows up as fans running at the wrong speed, humidity corrections that never arrive, and a controller that looks like it has failed when the sensor feeding it is the part that went. This probe is the answer to a room that keeps killing probes.
How to Use
- Turn off and unplug the controller at the wall.
- Disconnect the existing probe from the sensor port.
- Plug the high humidity probe into the same port.
- Site the sensor at canopy height, clear of direct spray from a humidifier.
- Power the controller back up and check the reading settles before relying on it.
