QMA2030

 Process Moisture Analyzer
A high-precision, fast-responding analyzer, which utilises advanced quartz crystal microbalance technology to offer drift-free measurement for a wide range of applications – from high purity industrial gases to catalyst bed protection.




Product Features

  • High accuracy: 5% in the range 0.5 to 700 ppmV
  • Wide operating range: 0.1 to 2000 ppmV
  • Extremely fast: less than 2 minutes for 63% response to a step change in either direction
  • Advanced Quartz Crystal Microbalance technology for drift-free measurements with low sensitivity to contamination
  • Automatic calibration for measurement confidence
  • Intuitive touch-screen easy-to-use front panel display
  • Low cost of ownership, simple maintenance
