In-situ Cross-Duct TDLAS Analyzer

LAS 300 XD-2

In-situ & non-invasive measurement of NH3 & H2O, HCl & H2O, HF, low or high concentrations of CO and O2

The Tunable Diode Laser Absorption Spectroscopy (TDLAS) is the perfect technology to use when you are looking for a selective measurement and a fast response time on specific gases such  as CO, O2, CH4, H2O, O2, HCl, HF, NH3….

Reliable, in situ low-maintenance gas measurement in stack monitoring and process applications


  • LAS 300XD-2 CO / O2 for carbon monoxide and oxygen monitoring (standard version)
  • Other gas combinations are possible; gases to be measured are to be selected from the following list: CO, CH4, H2O, O2, HCl, HF, NH3… (2 gases max.)
  • Tunable Diode Laser Absorption Spectroscopy (TDLAS) technique
  • In-situ and non-invasive measurement
  • Multi-gas cross-duct monitoring
  • Compact and robust system
  • Short response time: 2-5 seconds
  • High sensitivity
  • Interference-free gas measurements
  • Absolute measurements: no drift, no calibration required, linear response and high resolution
  • Suitable for harsh environments. Unaffected by contaminants – no contact with flue gas
  • No sample lines required, eliminating errors due to gas sampling
  • Low maintenance and low cost of ownership

Process & emission monitoring for:

  • Combustion control
  • Power utilities
  • Petrochemical industry
  • Waste incinerators
  • Cement industry
  • Glass industry
  • Pulp and paper
  • Biomass boilers
  • Steel manufacture, etc.
