LaserCEM
Laser infrared spectrometer

Certified and fully pre-calibrated multi-component gas analyzer for CEMS applications. Designed for medium to higher gas concentrations.


Functionality: Optical Feedback Cavity Enhanced Absorption Spectroscopy (OFCEAS) and Low Pressure Sampling (LPS)

  • Continuous multigas measurement
  • High resolution IR laser technology
  • Patented OFCEAS TDL technology
  • No optical moving parts
  • Certified measuring ranges for CO, NO, SO2, HCl, NH3, H2O, O2 fulfil IED requirements for waste incineration (WI) + large combustion plant (LCP)
  • Smallest certified measuring range for NO 0 … 78 mg/Nm3
  • Direct measurement without modifying the sample
  • Patented Low Pressure Sampling system
  • Low compressed air consumption
  • Multigas measurement without interferences regardless of the matrix
  • Measurement in very wet conditions (up to 80% vol H2O)
  • Zero information contained in the signal (no zero gas required)
  • Suitable for NOx ELV below 35 mg/Nm3 (WI) / 50 mg/Nm3 (LCP)
  • Very fast response time
  • Reduced operational costs (low compressed air + low power consumption due to self heated line at 80 °C)
  • High availability of the system
  • Incineration    
  • Cement
  • Combustion
  • Biomass
  • Flue gas treatment
  • Compounds and measuring ranges
  • Performances
  • Technical data
  • Application data
