The Easidew sensor is a moisture meter that measures both dew point and moisture content. It is simple to install as it is available with a wide range of process connections and electrical connectors. All Easidew dew-point transmitters are available with a service exchange program which reduces the cost and time spent on maintenance.
 
Reconfiguration of the transmitters is simple with the self-contained Easidew and Pura communications kit.
 
Michell’s Ceramic Metal-Oxide Moisture Sensor-based Hygrometers are calibrated to international standards and are delivered with a traceable calibration certificate.
