Overview
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. Optional Oxygen Electrochemical sensors offer additional capability for percentage and ppmV O2 measurements.
Single or multichannel configurations are available. The Control Unit in the multi-channel format can also include moisture in liquid analysis or oxygen measurement function by combining with the Liquidew I.S. Moisture in Liquid Analyzer or the Minox-i O2 transmitter
 | Suitable for use with natural gas containing up to 20% hydrogen with no further modification required. |
