FT-NIR Analyzers for Process and Field Measurements 


The FTPA2000-260 (formerly NetworkIR) is a proven near-infrared process monitoring analyzer for use with fiber optic sample interfaces. 





The analyzer is based on the proven single-pivot wishbone interferometer that was developed by ABB, providing unmatched performance with on-line process measurements.

  • Eight simultaneously illuminated fiber optic sample channels each with an independent detector
  • The Detector Module has no moving parts
  • Standard SMA fiber optic connectors
  • 19 ½” standard rack mount or wall mount
  • BK7 Optics
  • Health monitoring
  • The instrument is permanently aligned at the factory.
