Data sheet


The EE23 is a cost-optimized transmitter for industrial and high-end HVAC applications up to 120 ° C (248 ° F).

Relative humidity and temperature are precisely measured and the dew / gel temperature is accurately calculated.

Different models are available: wall, duct, remote sensor, as well as a version with miniature remote sensor for applications with limited space.

The three-piece design of a rugged polycarbonate or aluminum housing makes mounting and replacement easy.

The measurands are available on two analog outputs and an optional relay output.

The optional exclusive coating protects the sensor elements against corrosive and electrically conductive pollution.

On-site adjustment can easily be done with pushbuttons.
