Near Infrared Absorbance (NIR) Photometric H2O Analyzers


The CAI Model NIR 4000L utilizes the field-proven NIR Absorbance method to continuously detect water impurities found in solvents, acids, alcohols and glycols. 

The NIR 4000L incorporates a tungsten halogen lamp, 2 x fiber-optic cables, a flow-cell and InGaAs photodiode detector. These state-of-the-art optical components combine to deliver a highly reliable, continuous measurement of water in the liquid-phase. The NIR 4000L can readily be applied in the following applications:

  • 0-5% H2O in Ethylene Glycol.
  • 0-1% H2O in Acetone.
  • 0-1% Water in Methanol or Ethanol.
  • 0-10% Water in Acetic Acid.

CAI NIR Analyzer Highlights

  • Compact, space-saving configuration with no moving parts. Available for use in either hazardous or non-hazardous-rated areas.
  • High-pressure rated 316SS sample flow cell that is isolated from the controller electronics.
  • Optical design approach that compensates for source or detector aging.
  • Two-stage, TE-cooled InGaAs photodiode detector provides a highly sensitive and stable measurement of water in a variety of different backgrounds.
  • Touch-screen user interface provides diagnostic information vis-à-vis an automatic change in the concentration display color.
