The Easidew PRO I.S. Intrinsically safe dew-point transmitter measures moisture in demanding process and refinery applications in either gases or non-polar liquids.
Based on Michell’s Ceramic Metal-Oxide Moisture Sensor, the Easidew PRO I.S. gives long term stability and a fast response to changes in moisture. With high-volume manufacturing capacity, the Easidew PRO I.S. is suitable for use by OEMs and systems integrators, who require short and consistent lead times.
It offers a wide measurement range of –110 to +20 °Cdp, is easily integrated into existing systems and has global certifications for use in hazardous areas. The unit’s robust housing protects the electronics from harsh environmental conditions.
