Leaks in industrial gas systems can range from almost unnoticeable to disruptive and dangerous disturbances. Locating a leak in compressed air, gas, and vacuum systems can be challenging and time-consuming but quite necessary if the leak is to be repaired. Several gas detectors are available, using stationery and mobile or hand-held equipment to search for escaping emissions. In extreme cases, leaking gases may be toxic, with pressurized gases that include ammonia, chlorine, nitrogen oxide, and sulfur oxide that must be detected and monitored. In less severe cases, escaping gases such as oxygen (O2) may be safe to an operating environment, but a leak or leaks represent an ongoing expense in the loss of a resource.
Gas leaks can be found in numerous ways, often by pressure testing a gas storage unit or interconnecting hose to enable gas sensors to measure beyond their minimum detection limits. Numerous types of gas detectors, such as electrochemical sensors, infrared (IR) sensors, semiconductor
