Online Infrared Gas Detector

Online infrared gas detectors are based on the principle that gas molecules absorb infrared light at specific wavelengths. They calculate gas concentration by measuring changes in the intensity of transmitted light. These devices are used for continuous monitoring of combustible or toxic gases in industrial processes, ensuring production safety in chemical and environmental protection fields.
Selection
When selecting, confirm the infrared absorption characteristics of the target gas to match the instrument's detection range with the on-site concentration. Consider the explosion-proof rating and adaptability to environmental temperature, and check the sensor's ability to resist cross-interference. Verify that the output signal is compatible with the existing control system, and evaluate the maintenance cycle and ease of calibration.
