(CH₄) Passive Laser Online Monitoring System

(Methane) Passive Laser Online Monitoring System As a high-tech gas monitoring device equipped with Hanhai's proprietary passive core technology, it is specially designed for methane leakage monitoring in buried gas pipelines and multiple scenarios. Adhering to the core design philosophy of "passive intrinsic safety, underground coordinated deployment, and accurate real-time monitoring", the product innovatively adopts a "host transmission + optical fiber transmission + detection terminal" architecture. It thoroughly breaks through the power supply limitations and underground scenario deployment bottlenecks of traditional monitoring equipment, providing a full-life-cycle leakage monitoring solution for newly-built buried gas pipelines while meeting the safety monitoring needs of multiple fields.

With its world-leading passive monitoring design, the system perfectly solves the power supply problem of underground pipeline monitoring, avoiding monitoring interruptions of traditional equipment caused by battery depletion and difficult wiring. The terminals are resistant to soil corrosion, pressure and aging, enabling long-term stable operation in underground environments. Meanwhile, it supports synchronous planning, construction and commissioning with newly-built buried gas pipelines, eliminating the need for additional road excavation in later stages, thus significantly reducing engineering construction costs and construction cycles. A single host can connect to dozens of detection terminals to achieve continuous coverage monitoring of long-distance pipelines. As a core product of Hanhai Optoelectronics' technological innovation, the system redefines the technical standards for buried gas pipeline monitoring and becomes the preferred equipment for safety protection of newly-built pipelines in the gas industry. It also provides a high-tech solution for methane leakage monitoring in multiple fields, helping enterprises improve the intelligence level of safety management and prevent leakage risks.
