This product is an intrinsically safe laser methane sensor specifically designed for environmental monitoring in coal mines. Utilizing Tunable Semiconductor Laser Absorption Spectroscopy (TDLAS) technology and a 1653.7nm laser as the light source, it precisely targets the characteristic absorption peak of methane molecules, enabling real-time, online monitoring of methane gas concentration. The sensor is intrinsically safe and explosion-proof, and can be widely used for methane concentration monitoring in coal mine working faces, roadways, and return airflow areas.

Intrinsically safe design, mining certificationThe explosion-proof marking Ex ia I Ma (or Ex ia IIC T6 Ga) meets the inherent safety requirements of underground coal mines, ensuring safe operation in flammable and explosive environments.

TDLAS technology has strong anti-interference capabilities.It adopts the principle of laser spectral absorption, which has unique selectivity for methane gas, effectively avoiding interference from water vapor, other gases and poisoning factors, and the measurement results are true and reliable.

Wide temperature and pressure compensation, strong environmental adaptabilityBuilt-in temperature and pressure sensors enable real-time concentration compensation and correction, allowing for stable operation within a temperature range of -20℃ to +60℃, 86-118kPa, and 0-98%RH humidity.
