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

(Wired Type) Point Laser Methane Detector It is a laser-based monitoring product integrating low-power consumption technology, computer intelligent algorithms and waterproof & explosion-proof craftsmanship. Specially designed for methane safety monitoring in crowded places such as commercial complexes and hotels, it is also applicable to other industrial-grade environments. Adopting high precision & sensitivity, safety & durability, and easy integration as its core design philosophy, the product breaks through the limitations of traditional monitoring equipment in anti-interference performance and scenario adaptability, providing an all-weather, high-reliability solution for methane leakage monitoring and safety early warning of gas systems in crowded venues.
In terms of core technologies and performance, it integrates low-power consumption technology and a computer processing module, which ensures 24/7 stable operation while reducing energy consumption. Combined with wired transmission, it features fast data transmission speed and high stability, capable of uploading detection data and equipment status in real time. It avoids wireless signal interference issues and adapts to the complex wiring requirements of commercial scenarios. Strictly complying with commercial safety monitoring specifications, the product can maintain stable operation during long-term service in commercial venues. Widely applicable to gas safety monitoring in crowded places such as hotels, commercial complexes and catering establishments, it serves as a core monitoring device for improving the safety protection level of venues and safeguarding personnel's lives and property.

1. Core Industrial Production Scenarios
Energy and Chemical Industry: Natural gas processing plants, oil and gas gathering pipeline nodes, gas tank farms, and gas supply interfaces of chemical reactors.
Manufacturing Industry: Perimeter of gas-fired boilers/furnaces, gas pipeline valves in heat treatment workshops, and industrial gas storage rooms.
Power Industry: Gas generator rooms, key monitoring points of natural gas transmission pipelines, and supporting gas equipment areas.
2. Commercial and Public Building Scenarios
Commercial Complexes: Concentrated catering back kitchens, underground gas pipeline shafts, central air-conditioning gas machine rooms, and gas regulator stations.
Hotels/Office Buildings: Kitchen operation areas, gas heating equipment rooms, and gas interface nodes in pipeline shafts.
Medical Institutions/Schools: Canteen back kitchens, gas-fired hot water boiler rooms, and medical gas auxiliary equipment areas (requiring stable wired transmission).
3. Civil and Residential Supporting Scenarios
New Residential Communities: Beside residential kitchen gas meters/valves, around gas water heaters, and centralized gas pipeline shafts.
Large Community Supporting Facilities: Community canteens, heating gas machine rooms, and underground garage areas traversed by gas pipelines.
Affordable Housing/Apartment Buildings: Unified planned gas monitoring points in kitchens (suitable for wiring construction of new projects).
4. Gas Storage, Transportation and Municipal Scenarios
Municipal Gas Facilities: Gas regulator stations, valve chambers, and underground gas pipeline manholes (for long-term fixed monitoring).
Natural Gas Gate Stations/Storage Stations: Tank farms, loading and unloading operation areas, and high-pressure pipeline interface valves.
Key Nodes of Urban Pipe Networks: Trunk pipeline branch interfaces, and monitoring points of gas pipelines crossing rivers/railways.
5. Special Scenarios Requiring Stable Monitoring
High-safety Demand Venues: Canteens of military industrial units, gas laboratories of research institutions, and gas supporting areas in flammable and explosive environments (wired transmission with strong anti-interference capability).
Long-term Operation Scenarios: Unattended machine rooms, and gas booster stations in remote areas (wired power supply + more stable transmission).
Large-scale Parks: Concentrated gas consumption areas of industrial parks and logistics parks (compatible with the park's unified security wiring system).
It can accurately detect trace gas leaks with a fast response time. Upon an alarm triggered by minor gas leaks, early detection and disposal can be achieved promptly.
It features high monitoring accuracy and can completely eliminate false alarms, eliminating the need for re-inspection. This simplifies safety management, allowing immediate measures to be taken once an alarm is activated.
Calibration is not required, which addresses the problem of frequent adjustment needed for traditional monitoring equipment, and greatly reduces the workload of subsequent maintenance and operational costs.
Unaffected by humidity, dust, temperature and other gases, it can operate continuously in high-humidity environments for long periods.
