Handheld portable laser remote sensing methane detector

JK40-CH4-RS

1 Overview

The handheld remote methane telemetry instrument adopts TDLAS (laser spectroscopy) technology, which quantitatively measures the methane gas concentration in the target area by absorbing specific wavelength lasers through methane gas, and quickly monitors the methane gas concentration in the area. The handheld device can be carried by the inspection personnel and can flexibly and dynamically detect the methane concentration in the inspection area.

remote sensingThe laser methane telemetry instrument is internationally leading in terms of performance indicators, due to its obvious advantages in operating range, detection sensitivity, and endurance, making it suitable for inspecting methane leaks in large-scale industrial scenarios such as oil and gas.

Product Composition Diagramworking principleThe working principle of this product is that when the instrument is in operation, it emits a detection laser within a specific wavelength range (the center wavelength is also different for different gases being measured). The detection laser encounters a reflector (such as the ground, valves, pipelines, walls, etc.) and undergoes diffuse reflection, with some of the laser returning to the detection unit of the instrument. In the beam path, if there is a gas mass formed by the leakage of the measured gas, the gas mass will absorb the detection laser. The ratio of unabsorbed light to absorbed light is proportional to the concentration of the gas mass, and the concentration of the gas mass can be inferred by calculating this ratio.
