Open Path gas detection, also known as line-of-sight gas detection or perimeter gas detection is used to detect gas clouds passing over a distance of 200 meters. This technology consists of a transmitter and receiver which need to be placed in a direct unobstructed line across from each other of up to 200 meters distance.
There are different technologies available on the market such as lasers, UV and IR based units. All these units work on a basis of signal absorption by the gas which allows the unit to quantify the gas could in LEL per meter.
The most commonly used open path gas detectors are the units calibrated to detect gas leaks from hydrocarbon-based gases, C1 to C8 molecules. Another technology available in open path gas detection is Toxic gas detection. These units are able to detect gas clouds of H2S, NH3 and SO2.
The Spectrex Quasar Open path gas detection series offers sets that are capable of detection hydrocarbon gas leaks over a path length of 200 meters and toxic gas leaks over a path length of 60 meters.
All Spectrex Quasar open path gas detectors are factory calibrated with real gas to ensure the highest level of accuracy.
