What are portable gas analyzers used for?
Portable gas analyzers are used to measure gas concentrations in industrial environments such as biogas plants, sewage treatment facilities, landfills, and manufacturing processes. They help engineers monitor gas composition, improve process efficiency, and maintain environmental safety.
How do portable gas analyzers work?
Most portable gas analyzers use NDIR infrared sensing technology to measure gas concentrations. Each gas absorbs infrared light at specific wavelengths, allowing the analyzer to determine gas composition with high accuracy and minimal interference.
