Infrared analyser

Infrared analyser - IR 8000

Control of CO2 or N2O in ppm level  (CO/CO2 configuration possible for medical applications)


IR 8000 Infrared Analyser uses  NDIR photometry technology to perform the measurement of CO2 or N2O, in ppm level, in various gases. A CO/CO2 ppm configuration is also possible for medical applications.


The IR 8000 analyser uses a NDIR photometer to perform its measurements.
  • A gas filled-layered detector allows for a highly selective measurement in different sample gas mixture / applications.
  • The applied measuring principle NDUV absorption spectroscopy enables the IR8000 to detect even smallest concentrations.
  • The high stability of the measurement is achieved due to the design and the applied signal processing.
