Electronic hygrotherm
ETF 012
The electronic hygrotherm simultaneously monitors temperature and air humidity in enclosures and cabinets. Condensation is avoided by switching the heating and fans as required. In the design with an external sensor, this can be placed anywhere in the enclosure, enabling precise measurement.
- Adjustable temperature and air humidity
- Wide-range voltage
- High switching capacity
- Operating temperature down to -40 °C
- Optical status display
