CH4 methane sensor Gasboard-2500

tunable diode laser absorption spectroscopyfor air quality monitoringfor leak detection

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 pre-calibration over full temperature enable long-term stability in hazardous conditions and complex gas environments. It has been widely deployed for industrial process monitoring and control, environmental sensing, plant and infrastructure security such as underground pipe networks.
