LAS 5000XD In-Situ Cross Duct Gas Analyser

Preferred Communication Method
This field is for validation purposes and should be left unchanged.


The new LAS 5000XD cross duct analyser combines robustness and a fast response time (1 second), thus providing reliable measurements.

With no gas conditioning required, the laser-based technology is less prone to temperature influences and cross-interferences. Therefore, it provides accurate measurement in harsh industrial environments.

It measures parameters in cross duct applications in combinations such as:

  • NH3 + H2O,
  • HF,
  • CO + CO2,
  • O2,
  • HCl + H2O

Where is the LAS 5000XD Most Effective?

The in-situ TDLS (Tunable Diode Laser Spectroscopy) gas analyser has been designed for measuring process emissions where certification isn't required.

  • Ammonia slip control (DeNox)
  • Process and combustion control
  • HF emission control in aluminum plant
  • HCl/SO2 abatement control
  • Ethylene cracking furnace control
  • HCl level in semiconductor production
  • Ammonia concentration control in pet food, fertiliser plants, etc.


Why Choose the Laser Based LAS 5000XD?

  • No sampling system needed
  • There's no gas temperature influence
  • Gas matrix interference free
  • Calibration free measurement



  • New Embedded ClearPath functionality where interference of relative humidity, O2 or CO2 is removed in purging areas
  • Highly sensitive and selective measurement
  • High signal-to-noise ratio
  • No measurement drift
  • Response time 1 s
  • Large dynamic ranges from ppm to %
  • Real-time communication between Transmitter (Tx) and Receiver (Rx)



With an embedded web server, there is no dedicated software needed. The server provides quick access to service diagnostics and analyser settings.
