The ARD Series Remote Methane Leak Detector employs advanced Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology. It utilizes the diffuse reflection of an emitted laser beam from the target surface combined with the selective absorption of a specific wavelength by methane gas molecules. This enables rapid, non-contact remote detection of methane leaks, making the detector particularly well-suited for hazardous or inaccessible areas where direct personnel access is not feasible.
Detector Principle
Feature：
· Higher detection sensitivity enables reliable identification of minute methane leaks.
· Faster response time allows rapid capture of transient methane plumes, making it ideal for mobile inspection patrols.
· Integrated self-calibration reference chamber eliminates the need for manual calibration.
· Extended detection range is specifically designed to accommodate high-rise buildings and complex urban gas distribution environments.
