MDM300 & MDM300 I.S. (Intrinsically Safe)

 Geavanceerde dauwpuntmeter

A high-speed portable dew-point hygrometer, offering rapid spot-check measurements of dew point or moisture content in many applications, including compressed air, natural gas and highvoltage switchgear quench gas. This lightweight, ATEX, IECEx, FM, CSA, GOST and INMETRO certified product allows more measurements per working hour than any other comparable product. A hard-wearing but ergonomic case and an easy-to-use interface allows comfortable and practical operation in the toughest industrial environments.
