DBK EHT-2 Digital Electronic Hygrostat

This second generation unit combines an idustry leading humidity sensor accuracy of 3% as well as high precision temperature sensor. The unit can work in either NC or NO mode and provides an extra dry contact which can be used to either switch an independent load or to act as a feedback contact for a PLC. Avanced features as the functionality of a fixed thermostat have been added to this unit. A two colored LED indicates operation mode as well as several error states. By default, the temperature setting is fixed at 4ºC to provide additional frost protection to enclosure electronics.
