TDLAS CH4 Sensor
Gasboard-2500Gasboard-2500

Gasboard-2500 is a methane gas sensor based on self-developed Tunable Diode Laser Absorption Spectroscopy(TDLAS) technology. This technology's high sensitivity and selectivity，as well as our precalibration over full temperature enable long term stability at hazardous conditions and complex gas environment. It has been widely deployed for industrial process monitoring and control, environmental sensing, plant and infrastructure security such as underground pipe network.
