A wide variety of non-polar liquids can be measured continuously, on-line, including flammable liquids and hazardous area applications, petrochemicals, power industry and pharmaceutical manufacturing. 

Features:

  • Simple, cost-efficient operation and low maintenance
  • Retrofit functionality, easy to integrate into existing sampling or distribution systems
  • High integrity moisture in liquid measurement from 0.01 ppmW to saturation point
  • Multi-channel with up to four completely independent measurement channels
  • Robust design for undisturbed operation in many non-polar liquids over a long time
  • Two 4-20 mA configurable outputs and digital Modbus RTU-based communication
  • Replaceable sensor element with Michell Calibration Exchange Service for reliable cost-efficient calibration
  • NIST and NPL traceable calibration
  • EExd version available
