Product Overview

The SLTD-CH4-100 Laser Methane Remote Sensor (hereinafter referred to as "the sensor") is independently developed by Shanghai Sangbay Sensor Technology Co., Ltd. The sensor is based on Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology, which offers significant advantages over traditional chemical and infrared spectroscopy absorption (NDIR) technologies, including:High sensitivity, capable of detecting minute leaks;High accuracy, unaffected by other gases;Easy maintenance, no need for frequent calibration;Faster response speed and longer service life; Utilizes the laser's excellent directionality and long-distance remote sensing capability to achieve active long-distance monitoring, changing the original passive monitoring method that relies on diffusion or pump suction, without waiting for leaked gas to diffuse to the monitoring equipment;Low false alarm rate and high reliability, sensitive only to methane gas, unaffected by insecticides, alcohol, paint, other alkanes, etc., suitable for environments with complex background gases.

Application Field

  • Gas Safety Inspection: Vehicle-mounted or handheld inspection for urban underground pipe networks, valve wells, and pressure regulation stations;
  • Oil and Gas Industry Monitoring: Leak detection and carbon emission monitoring for long-distance pipelines, storage tanks, and oil/gas field facilities;
  • Environmental Protection and Carbon Accounting: Precise monitoring of fugitive methane emissions at landfills, wastewater treatment plants, and other locations;
  • Industrial Safety Prevention: Long-distance safety scanning in chemical parks, tunnel corridors, and hazardous areas to protect personnel and facilities;
  • New Platform Integration: Mounted on drones and robots for three-dimensional intelligent inspection in complex environments (such as mountainous pipelines, factory rooftops).
