ETF 012 Enclosure Humidity and Temperature Control

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.

Features

• DIN Rail Mounting
• Adjustable Humidity Setpoint
• N.O. & N.C. contacts for heating or cooling & humidity
• SPDT (Change-over) contact
• Finger safe Screw Terminals IP20
• Wide adjustment ranges
• High switching capacity
• Optical function displays (LED)
• Efficient temperature & humidity control
