(C₂H₂) Fixed Reflective Laser Gas Telemeter It is an industrial-grade high-safety detection device integrating the core technology of Tunable Diode Laser Absorption Spectroscopy (TDLAS) and the reflective monitoring principle, specially designed for the fixed-point and accurate monitoring of acetylene gas. Adopting directional focusing, high-sensitivity capture and stable unattended operation as its core design philosophy, the product breaks through the limitations of traditional monitoring equipment in specificity, sensitivity and scenario adaptability, and provides an all-weather, high-reliability solution for leakage early warning and concentration monitoring of acetylene in high-risk fields involving acetylene production, storage, transportation and utilization, such as petrochemical industry, metallurgy, gas supply and fine chemical industry.
It adopts a fixed reflective monitoring architecture. By matching with dedicated weather-resistant reflective targets, the laser beam forms a stable monitoring optical path after reflection, enabling directional focused monitoring of specific pipeline sections, equipment nodes, acetylene cylinder storage areas or high-risk zones. The detection distance can be flexibly adapted to scenarios, featuring fast response speed and accurate positioning. It can feed back concentration data in real time, winning golden time for safe disposal. Widely applicable to scenarios such as acetylene production unit monitoring in the petrochemical industry, safety protection of acetylene cutting processes in the metallurgical industry, acetylene transmission pipeline monitoring in chemical parks, early warning of acetylene storage facilities in gas stations, and reaction process monitoring in the fine chemical industry, it serves as a core monitoring device for enterprises to prevent acetylene leakage risks, protect personnel's lives, and improve the intelligence level of safety management.

Metal Processing: Acetylene cylinder leakage early warning in welding/cutting workshops, shipyards and steel structure factories (suitable for workshop scenarios with high dust content and long-distance monitoring requirements).
Semiconductor/Electronic Manufacturing: Leakage monitoring of acetylene as a reaction gas in chip packaging and plasma etching processes.
2. Energy and Chemical Storage & Transportation
Hazardous Chemical Logistics: Real-time leakage monitoring of acetylene tank trucks, container loading and unloading areas and port terminals (to ensure the safety of logistics hubs).
Chemical Industry Park Pipe Rack: Leakage Monitoring of Acetylene Transmission Pipelines and Underground Utility Tunnels
Gas Cylinder Storage Depot: Long-distance safety monitoring of centralized acetylene cylinder storage areas (to avoid the risk of close-range contact for personnel).
Chemical Park Security: Acetylene leakage early warning at the boundaries of key chemical enterprises (to build a park safety protection network).
3. Scientific Research and Special Fields
Laboratory Safety: Acetylene gas leakage early warning in chemical laboratories of universities and research institutions (suitable for high-precision monitoring requirements).
Military Industry/Aerospace: Acetylene leakage and emission monitoring in special material synthesis and aerospace propellant-related processes.
Metallurgical Industry: Leakage monitoring of acetylene as a shielding gas in blast furnace smelting and continuous casting and rolling processes.
Unlike the passive waiting mode of traditional detection methods, it actively monitors potential gas leak points. With a response time of only 1 second, it can accurately detect ppm-level trace leaks, truly achieving preventive monitoring of gas leaks.
Compared with traditional detectors that are prone to interference from environmental factors, cross gases and other elements, it features strong anti-interference capability. It adopts fingerprint-based detection technology to realize genuine zero false alarms.
It quickly obtains the concentration value of leaked gas through the spectral inversion algorithm, with a sensitivity as high as 1 ppm·m, completely eliminating false alarms and missed detections.
