TDLS (Tunable Diode Laser Spectrometry) gas analysis modules are a new generation of ultra-high precision gas detection products which are suitable for coal mine, chemical industry and other industries. Based on the principle of laser spectral absorption, the modules have

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

These modules are capable of continuous detection of the gas concentration. The modules have RS485 communication interface and use Modbus communication protocol.

Gases measured using these modules include:
NH3
HCL
HF
H2S
CH4
CO
CO2
02
