The measurement principle of TDLAS T-1 is based on the Lambert-Beer law and Shinyei’s new technology.
TDLAS T-1 achieves outstanding response and highly reliable accuracy in wide range of dew point.

  • Outstanding response suitable for immediate H2O measurement
  • Highly reliable accuracy besides fast response
  • Wide measurement range: -70…50 °C DP (Dew Point)
  • Built-in pump for gas sampling
