EmailThe PGA-6000 Process Gas Analyzer is a high-precision explosion-proof laser gas analyzer with multiple reflections, developed based on tunable diode laser absorption spectroscopy (TDLAS) technology. It can analyze various gases such as O₂, CO, H₂S, and CO₂, and is applicable to Zones 1 and 2 of explosive gas environments. This product uses an imported semiconductor laser as the light source, and near-infrared or mid-infrared lasers can be selected according to the type of gas to be detected and the measurement range required.
