Optical gas Detector

Optical gas detectors operate based on the absorption characteristics of gas molecules for specific wavelengths of infrared light, calculating gas concentration by measuring the attenuation of light intensity. They are used for real-time monitoring of harmful gases in the environment, ensuring production safety in chemical and environmental protection industries.
Selection
When selecting, consider the detection gas types and the range to match on-site requirements, and pay attention to the instrument's response speed and detection limits. Verify that the explosion-proof rating is suitable for the working conditions, and check the sensor's anti-interference capability. Assess the data output interface's compatibility with existing systems, and perform regular calibration and maintenance to ensure measurement stability.
