Open-path laser gas Detector

Open-path laser gas detectors work by emitting a laser beam through an open space, where gas molecules absorb light at specific wavelengths, causing attenuation of the light intensity. The detector analyzes the degree of attenuation to calculate the gas concentration. They are used for large-scale leak monitoring in places like chemical plants and storage tank areas, enabling non-contact continuous measurement.
Selection
When selecting, consider the detection distance and coverage to match site requirements, confirm that the laser wavelength corresponds to the target gas absorption spectrum line, ensure the protection rating is suitable for the on-site environment, verify data interface compatibility with existing systems, and conduct regular calibration and maintenance to ensure measurement consistency.
