Introduction
IR-GAS-600 series gas analyzer is an non-dispersive infrared (NDIR) gas analyzer. Moreover, the NDIR gas analyzer independently developed by our company for environmental monitoring and industrial site emission gas analysis. The analyzer mainly measures CO, CO2, CH4 ,N2O and O2 gas concentrations, and has the characteristics of high measurement accuracy, high stability and reliability and fast response time.
This model high-stability infrared detectors for simultaneously measuring CO, CO2, and CH4. H2 always reads correctly, independent of the background gas composition. An optional non-depleting paramagnetic sensor can be used to conduct O2 analysis. All sensors/detectors are temperature-controlled or temperature-compensated for maximum analytical stability.
Both types of analyzers are available with analysis of:
☑ Measure COppm+CO2+CH4ppm+N2Oppm in the one unit
☑ Measure CO%+CO%+CO2%+CH4%+CnHm% in the one unit

We detect CO, CO₂, CH₄, C₃H₈, and other molecular species—composed of heterogeneous atoms—by measuring their infrared absorption spectra. Specifically, when a gas absorbs infrared radiation at its characteristic wavelength, it attenuates the transmitted signal. According to Lambert–Beer’s law, the degree of attenuation directly correlates with the gas concentration. Consequently, we quantify gas concentration by measuring the extent to which absorption intensity diminishes at those characteristic wavelengths. The basic principle of the NDIR sensor structure, shown below,
