High Accuracy TDLS Modules for Gas Detection

TDLS (Tunable Diode Laser Spectrometry) gas analysis modules are a new generation of ultra-high precision gas detection products which are ideal for the chemical industry, coal mining and other industries.

CH4 TDLAS Module

TDLS (Tunable Diode Laser Spectrometry) gas analysis modules are based on the principle of laser spectral absorption.  The modules have:

  • High measurement accuracy
  • Wide range
  • Long service life
  • Quick response time
  • Excellent stability
  • Internal temperature compensation and cross interference compensation

Modules have RS485 communication interface & use Modbus communication protocol

Gases measured using these modules include:

  • NH3
  • HCL
  • HF
  • H2S
  • CH4
  • CO
  • CO2
  • 02
