Product Detailed
Electronic Hygrothermostat ETF 012 Temperature and humidity adjustable LED display High switching capacity Clip fixing

ETF 012 Electronic Hygrothermostat


Temperature and humidity adjustableOptical operating display LED

High switching capacityClip fixing 

The electronic hygrotherm senses the ambient temperature and relative humidity in an enclosure with electric/electronic components, and turns on a heater (or alternatively, a fan) at either set point, helping prevent the formation of condensation in the enclosure. The LED integrated in the adjustment knob on the active controller is lit when the connected device is in operation.
