The ESEGAS IR-GAS-600 is a multi-gas analyzer using non-dispersive infrared (NDIR) technology for continuous measurement of selected infrared-active gases. It combines stable infrared detection with configurable measurement ranges to support industrial process monitoring, gas composition analysis and environmental applications.
Optional measurement channels for hydrogen and oxygen allow users to build an integrated multi-component gas analysis solution
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

NDIR gas analyzer 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,
