±3%RH Outdoor Sensor for HVAC
A reliable basic outdoor humidity sensor for a pole or wall installation. Dew point, wet bulb and enthalpy outputs can be selected by dip switch instead of the default RH output.
The Humidity and Temperature Sensor Transmitter Series HMS80 are optimized for outdoor measurements HVAC. They feature an integrated solar radiation shield, which is a must for accurate humidity and temperature measurements in outdoor conditions. Both 2-wire HMS82 and 3-wire HMS83 versions are available.
Key Benefits
Easy Installation
The HMS80 can be mounted directly to a wall or pole without any extra accessories.
Low Maintenance
The INTERCAP sensor can easily be replaced in the field with minimum downtime.
Integrated radiation shields
The radiation shields reduce the influence of solar radiation on temperature and humidity measurements
