Enviro - Model LEA300 Series -NDIR Gas Analyzer
LEA300 series gas analyzer is an infrared 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.
IR-GAS-600 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:
- Carbon Monoxide (CO) via infrared detector
- Carbon Dioxide (CO2) via infrared detector
- Oxygen (O2) via electrochemical sensor or optional paramagnetic
- Methane (CH4) via infrared detector
Measure COppm+CO2+CH4ppm+N2Oppm in the one unit
Measure CO%+CO%+CO2%+CH4%+CnHm% in the one unit

CO, CO2, CH4, C3H8, and other molecules by heterogeneous atoms in the infrared wavelength region with the absorption spectrum, its absorption intensity follows Lambert – Beer’s Law. When corresponding to a characteristic absorption wavelength of the light waves of gas through the gas is measured, its intensity will be significantly weakened, and the intensity of the gas concentrations in the degree of attenuation related to the relationship between compliance with Lambert-Beer law. The basic principle of NDIR sensor structure, shown below,
