Hanhai Opto-electronic is a major scientific research achievement transformation institution of the Hefei Institute of Physical Science, Chinese Academy of Sciences.

(CO) Fixed Reflective Laser Gas Telemeter It is an industrial-grade high-safety monitoring 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 carbon monoxide 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 carbon monoxide in high-risk fields involving carbon monoxide generation, storage, transportation and utilization, such as petrochemical industry, metallurgy, mining, electric power and urban gas supply.
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 focusing monitoring of specific pipeline sections, equipment nodes, confined spaces or high-risk areas. The detection distance can be flexibly adapted to scenarios, featuring fast response speed and high data stability. It can feed back concentration data in real time, winning golden time for safe disposal. Widely applicable to scenarios such as carbon monoxide production unit monitoring in the petrochemical industry, safety protection of smelting processes in the metallurgical industry, carbon monoxide concentration early warning in underground mines, boiler exhaust gas monitoring in the electric power industry, and associated monitoring of urban gas leaks, it serves as a core monitoring device for enterprises to prevent carbon monoxide leakage risks, protect personnel's lives, and improve the intelligence level of safety management.

1. Industrial Safety Monitoring
Chemical Industry Parks: Monitoring the leakage of process tail gas from synthetic ammonia, methanol production, etc., as well as the atmospheric diffusion around workshops.
Coal Mining Industry: CO concentration early warning in underground roadways and gas drainage areas at wellheads (to avoid poisoning/explosion risks).
2. Environmental and Ecological Monitoring
Urban Air Quality Monitoring: Tracing the sources of CO pollution around main traffic arteries and industrial parks (vehicle exhaust and industrial emissions).
Landfills: Monitoring the leakage of landfill gas (containing CO) to prevent soil/atmospheric pollution.
Confined Space Pre-treatment: Long-distance detection of whether the internal CO concentration in underground tunnels, mines and storage tanks exceeds the standard.
3. Special Venue Security
Warehousing and Logistics: CO leakage early warning in flammable goods warehouses and chemical storage areas.
Municipal Facilities: CO concentration monitoring in urban underground utility tunnels (gas cabins) and tunnel ventilation systems.
Military Industry/Scientific Research: Monitoring the process emissions and leakage of CO in special laboratories and military production workshops.
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.
