Infrared PHA gas analyzers are designed to measure the volume fraction of methane (CH4), propane (C3H8), carbon dioxide (CO2), oxygen (O2), hydrogen (H2) and the mass concentration of carbon monoxide (CO), hydrogen sulfide (H2S), sulfur dioxide ( SO2), nitrogen dioxide (NO2), ammonia (NH3) and the sum of saturated hydrocarbons Σ (C2-C10). The PHA gas analyzer has a portable design with sensors integrated in the housing. The gas analyzer is designed to ensure industrial safety and control the content of various substances in the air of the working area. There are 96 modifications of infrared PHA gas analyzers,
