Intrinsically safe moisture in liquids analyzer for fast, reliable on-line measurements. Continuous online measurement allows monitoring and control of processes to maximise efficiency for production and maintenance.
Based on the Michell Ceramic Metal-Oxide Moisture Sensor, Liquidew I.S. measures trace moisture in a wide variety of non-polar liquids. It is fully certified for use in hazardous areas and typical applications include control of moisture for petroleum refineries and petrochemical processing. Optional Oxygen Electrochemical sensors offer additional capability for percentage and ppmV O2 measurements.
The control unit in the multi-channel format can also include a moisture in gas analysis or oxygen measurement function by combining with the Promet I.S. Moisture in Gas Analyzer or the Minox-i O2 transmitter.
