The Easidew I.S. (intrinsically safe) transmitter is a dew-point
transmitter designed and certified for use in hazardous area
applications (flammable or explosive gases) in all regions with
certification from: IECEx, CSA, FM and ATEX.
The Easidew I.S. is available with a 5/8" UNF process
connection or alternatively with a G1/2" BSP or 3/4"
UNF process connection. It is designed for ease of use,
incorporating all of the features needed to make installation
and operation into your air or gas management system as
simple as possible.
Michell's Advanced Ceramic Moisture Sensor technology based
transmitter is calibrated to international standards and is
delivered with a traceable calibration certificate.
