Questions about our products?

The EE23 is a cost optimised transmitter for industrial and high-end HVAC applications up to 120°C (248°F). Relative humidity and temperature are accurately measured and dew/frost point temperature precisely calculated.

Various models are available including wall, duct, remote probe as well as a version with miniature remote probe for applications with limited space. The three-part design of rugged enclosure in polycarbonate or aluminium allows easy mounting and replacement.

The measurands are available on two analogue outputs and an optional relay output. The optional proprietary coating protects the sensor elements against corrosive and electrically conductive pollution. Field adjustment can be easily performed with push buttons.
