Product description
The handheld small laser methane leak detector uses TDLAS (laser spectroscopy) technology to quantitatively measure the methane gas concentration in the target area through the absorption of specific wavelength laser by methane gas, and quickly monitor the methane gas concentration in the area. The product has the characteristics of precise selectivity, high sensitivity, high precision, low false alarm rate, strong anti-interference, and easy operation for methane gas monitoring. The handheld instrument can be carried by inspection personnel, which provides great convenience for the safety inspection work and can flexibly and dynamically detect the methane concentration in the inspection area.

Working principle
The handheld small laser methane leak detector adopts tunable laser spectroscopy (TDLAS) technology, which uses the characteristic absorption principle of a specific wavelength laser when irradiating characteristic gases. It controls, analyzes and calculates the distribution between the device and the target through the microcontroller control circuit. The characteristic gas methane concentration between the point paths, and its actual measured value is output through the feedback circuit.
This equipment can accurately measure and analyze characteristic gases truly and effectively without being interfered by other gas components. That is to say, the device can only perform testing functions for methane gas, and will not react to other gases such as ethane, propane, water gas, etc.
