FTA54+

Outdoor sensor for measuring humitiy and temperature in HVAC applications, greenhouses, industrial halls and in meteorology.
Alternatively to relative humidity the output can be set to absolute humidity, enthalpy or dew point. 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.
