Product Description

Promet I.S. Process Moisture Analyzers are heavy duty, industrial hygrometer systems for measurement of high pressure, process gases and vaporized liquids on natural gas platforms and terminals, petrochemical plants and industrial gas manufacturing facilities. Promet I.S. combines Michell’s proven Ceramic Metal-Oxide Moisture Sensor with ES70 sample conditioning systems to provide a reliable and easy to operate, multi-channel on-line instrument for both flammable and non-flammable gases.

Single or multichannel configurations are available. Up to four Promet I.S. or Liquidew I.S. moisture in liquid analyzers may be combined via the multi-channel control unit.
