EA2 TX Dew Point Transmitter for Compressed Air 05536

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.
