FTK+ relay / LCD / BUS

Duct sensor for measuring relative and absolute humidity, enthalpy, dew point and temperature in gaseous media of heating, ventilation and air-conditioning systems as well as in clean room technology. The devices with relay output for a 2-point controller or a 2-stage 2-point controller and color-changing LCD allow a wide range of applications. Depending on the model, the sensor can be individually configured via Thermokon USEapp. Accuracy of the humidity sensor is 2%. Tool-free opening, closing and wiring as well as removable cable entries ensure quick and easy installation.
