Wall-mounted temperature/humidity HN-EK

The HN-EK series is a high-performance, highly reliable wall-mounted temperature/humidity with two-wire transmission system that uses a polymer capacitance humidity sensor development in-house. It can be mounted on an indoor wall to measure temperature/humidity.

Wall-mounted temperature/humidity for indoor environment management and air conditioning management

Measurement temperature: -10 to 55°C
Reduces the effect of heat conduction from the mounting wall, enabling more high accuracy temperature/humidity measurement
Slim design that can be installed anywhere
The sensor unit is a fully interchangeable type, so only the sensor unit can be replaced, making maintenance easy.
analog output signals are DC 4-20mA for both relative humidity and temperature. Models with temperature output as Pt100 (3-wire resistance thermometer output) are also available.

Main Applications

Clean Room
Office Air Conditioning
Store air conditioning
Pharmaceutical companies
Animal Breeding Room
Hundred-use box
