Open-path Laser Natural Gas Leakage Detector
1.Product Overview
The open-path laser natural gas leakage detector Discovery-01 is a new type of gas detection instrument developed by our company. It is an outdoor-use product. It is currently a technologically advanced open-type laser gas detector and has been installed in multiple challenging and harsh environment industrial applications. Discovery-01 is a high-precision instrument designed based on the principle that methane gas has an absorption effect on specific wavelengths of laser (TDLAS). It adopts long-life laser and micro-control technology, combined with excellent SMD manufacturing process. It has excellent repeatability and temperature/humidity characteristics, as well as a long service life and convenient operation.
2.Product Features
(1) Unique output waveform, pulse duration is only 1 to 2 ms, strong anti-interference ability.
(2) With complete self-check function, corresponding fault alarm signals are output.
(3) High measurement accuracy, stable performance, long service life.
(4) 4-20mA standard analog signal output.
(5) Professional matching installation bracket, easy and convenient for on-site installation.
(6) Fast response speed, high sensitivity.
(7) The measurement distance is relatively long, the farthest can reach 200m.
3. Application
The petroleum, petrochemical, oil refining, chemical, metallurgical industries, and power sectors.

5. FQA
Why choose open-path gas detection?
(1) A wider coverage area can detect any leakage.
(2) Detection is carried out within a linear area ranging from 0 to 200 meters.
(3) The response is fast, allowing for understanding of the cumulative concentration of the gas cloud.
(4) It does not cause poisoning, no calibration is required, and the maintenance volume is small.
(5) It can understand the diffusion of the gas when the wind direction changes.
