Methane sensor Gasboard-2502

opticalTDLASfor air quality monitoring

Gasboard-2502 is developed based on Tunable Laser Absorption Spectroscopy (TDLAS) technology, which is a high-precision optical measurement technology that achieves ultra-low detection limit and high resolution through multiple reflections in a long optical path. Aiming at low-concentration methane leakage in the atmospheric background, Gasboard-2502 can achieve highly selective and accurate methane leakage detection, with a minimum detection limit of 1ppm and a resolution of 0.1ppm. Furthermore, it boasts fast response times with a warm-up time of less than 10 seconds. Based on the temperature compensation algorithm and self-diagnosis function, it ensures stable performance even in harsh working conditions and complex environments. In addition to its core performance features, Gasboard-2502 also has an intelligent power consumption design and a long lifespan of more than 10 years. Due to its modular structure, it is easy to integrate into a fixed detector that can be applied in oil and gas industry for methane emission monitoring.
