Spectra Sensors TDLAS Analyzer

Item Code: SS2100


Using patented tunable diode laser absorption spectroscopy (TDLAS) technology, the SS2100 gas analyzer measures specific gases (H2O, CO2, H2S, NH3, and C2H2) with precision while avoiding interferences that are common with traditional infrared analyzers. The SS2100 analyzer requires little maintenance and does not need recalibration or periodic replacement parts.


  • Accurate real-time measurement

  • Low cost of ownership, no consumables and virtually maintenance-free and reliable in harsh environments

  • Available to measure up to 3 analytes in one unit (2-packs or 3-packs)

  • Provides measurements not hampered by wet-up (absorption) or dry-down (desorption)

  • No contamination or drift due to vapor impurities such as glycol, methanol, amines, hydrogen sulfide, or mercaptans

  • Dependable with greater repeatability than surface-based sensors

  • Analog and serial outputs for remote monitoring

  • Available for following measurements: H2O, CO2, H2S, NH3, C2H2
