Open-path flammable gas Detector

The open-path combustible gas detector identifies leaks by emitting an infrared beam and detecting the attenuation of light intensity caused by gas absorption. It is used for large-scale area monitoring in chemical plants, oil depots, and other facilities, covering distances of up to a hundred meters and maintaining detection sensitivity even under windy conditions.
Selection
When selecting, consider matching the detection distance with on-site obstructions, confirm that the instrument's explosion-proof rating is suitable for the environment, check false alarm rate data, compare cross-interference parameters for different gases, verify the impact of environmental temperature on beam stability, and ensure that alarm thresholds are adjustable.
