Electronic Hygrothermostat
Product name : Electronic Hygrothermostat
Item : ETF 012
Details :
|
|
- Temperature and humidity adjustable
- Optical operating display (LED)
- High switching capacity
- Clip 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.
