TDLAS CH4 Sensor for Fuel Gas Pipeline
Gasboard-2501Gasboard-2501

Gasboard-2501 series methane sensor is a high-performance gas sensor based on tunable laser absorption spectroscopy technology (TDLAS). Using high-performance probes and special processing gas chambers, Gasboard-2501 TDLAS CH4 sensors have the characteristics of high precision, high sensitivity, long life, stable performance, etc. Also with the temperature compensation algorithm, TDLAS Gasboard-2501 could not be impacted by environment interference, and can work stably in harsh working conditions and complex gas environments. Gasboard-2501 TDLAS CH4 sensor adopts modular design and is easy to be integrated and maintained. It has been largely used in underground pipelines, fuel gas pipelines, fuel gas valve well, fuel gas pressure regulation cabinets, etc.
