TDLAS CH4 Sensor
Gasboard-2501 SeriesGasboard-2501 Series

Gasboard-2501 methane sensor is high-performance gas sensor based on tunable laser absorption spectroscopy technology (TDLAS).

Adopting a narrow-band tunable laser source, special gas chambers and optical path design, Gasboard-2501 offers superior methane gas selectivity and strong resistance to interference from water vapor and other gases, even under complex background conditions or high humidity, guaranteeing highly accurate and stable measurements. It achieves high accuracy of ±5%LEL across the measurement range of 0-100%LEL and operating temperature range of -25°C~+55°C.

Gasboard-2501 delivers fast response times, capturing fluctuations in methane concentration. With inherent stability of laser-based detection, the sensor provides long-term operation without significant drift, with a long life over ten years, significantly reducing the need for maintenance and recalibration. Engineered for low power consumption, Gasboard-2501 is suitable for deployment in continuous, long-term industrial monitoring.

To ensure safe deployment in hazardous zones, Cubic Gasboard-2501 is ATEX and IECEx Ex ia IIC T4 Ga certified. It can be widely applied in oil & gas industry, mining, energy sector, landfill sites, sewage treatment plant, refineries, fuel storage facilities, LNG transportation, gas pipeline leak detection, greenhouse gas emission quantification.
