Electronic Hygrothermostat ETF 012 Temperature and humidity adjustable LED display High switching capacity Clip fixing
ETF 012 Electronic Hygrothermostat
1.Features:
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.
