Infrared analyser IR 8000

gasN2Omonitoring

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. Principle 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.
