Carbon Dioxide Gas Analyzer

Carbon dioxide analyzers detect the concentration of CO2 in gases using the infrared absorption method, which relies on the absorption characteristics of CO2 molecules for specific wavelengths of infrared light to perform quantitative analysis. They are used in environmental monitoring, industrial process control, and laboratory gas detection to ensure production environment safety and process stability.
Selection
When selecting, consider whether the measurement range matches the application scenario, whether the response speed meets detection requirements, and whether the accuracy satisfies usage needs.
