Application
The product is suitable for workplaces that require gas leakage monitoring, such as coal and its chemical industry, petroleum and petrochemical industry, natural gas, mining, power plants, etc. It can be used for monitoring gas concentration content, inspecting gas pipeline networks, inspecting outdoor natural gas pipes, and inspecting natural gas storage tanks. Remote detection can be carried out in areas with gas leakage hazards and areas that are difficult for personnel to reach.
Typical application methods: Inspection of production facilities, mines, oil and gas pipelines, long-distance pipelines, underground pipe galleries, and other key locations in the factory area.
Frequently Asked Questions
QWhat detection technology does this scanning standoff methane laser detector use?
The detector is based on tunable laser absorption spectroscopy (TDLAS) technology, which enables non-contact, high-sensitivity measurement of methane (CH4) concentration. This principle delivers fast response times of ≤0.1 s with no direct physical contact with the gas medium required.
QWhat is the maximum detection distance and measurement range?
The device supports a detection distance of 0m to 150m and a measurement range of 0~50,000 ppm·m. This long standoff capability allows personnel to safely monitor hazardous zones from a distance without entering the danger area.
QWhat scanning coverage does the device provide?
The device offers full 360° horizontal scanning and -90° to +90° vertical scanning from a single fixed installation point, enabling wide-area continuous coverage with no blind spots in the monitored zone.
QIs this detector certified for use in explosive or hazardous environments?
Yes. The detector holds an explosion-proof certification of Ex db lIC T6 Gb and an IP68 weatherproof protection rating, making it fully suitable for outdoor, corrosive, or intrinsically hazardous industrial environments such as petrochemical plants, gas pipelines, and mining sites.
QDoes the device require manual on-site calibration or standardization?
No. The device supports automatic calibration and is factory-standardized, so no repeated on-site standardization is needed. This significantly reduces maintenance overhead and ensures consistent measurement accuracy over long-term operation.
QWhat industries and applications is this product designed for?
The detector is designed for a broad range of industries including coal and chemical processing, petroleum and petrochemical facilities, natural gas distribution, mining, and power generation. Typical deployments include production facility perimeters, oil and gas pipeline inspection, underground pipe galleries, storage tank monitoring, and remote or hard-to-access locations with gas leakage risk.
