The MDM300 I.S. is an advanced portable dew-point meter designed for fast, reliable on-site spot-check measurements of dew point and moisture content across a wide range of industrial applications. Built with Michell's proprietary ceramic impedance sensor technology, it delivers exceptional accuracy, fast response times, and rugged durability for demanding field conditions.
The MDM300 I.S. is certified for use in hazardous areas with ATEX, IECEx, FM, CSA, and GOST approvals. A junction box is included for connecting to Michell Easidew TX I.S. or Easidew PRO I.S. transmitters for calibration verification without process shutdown. The standard MDM300 is also available for non-hazardous applications.
The MDM300 supports a wide range of sampling configurations from simple low-pressure fixed-orifice setups to fully configurable high-pressure systems rated to 350 barg. Application-specific sampling kits available for compressed air, medical gases, SF6 switchgear gas, and natural gas.
