The maintenance-free and multifunctional duct air quality sensor measures mixed gas (VOC), optionally temperature and humidity (relative, absolute, enthalpy, dew point). Further possible features, such as a relay output for a 2-point controller or a 2-stage 2-point controller, LCD with traffic light indication allow for a wide range of applications. Depending on the model, the sensor can be configured individually via Thermokon USEapp. A hinged cover and tool-free wiring as well as removable cable entries ensure a quick and easy installation.
