Adopting advanced Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology with a long optical path design, Gasboard-2502 methane measurement sensor could achieve high-resolution methane measurements for quantitative continuous emission monitoring.
Cubic Sensor 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. Based on the temperature compensation algorithm and self-diagnosis function, the methane detection sensor 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 be integrate into a fixed detector that can be applied in the oil and gas industry for continuous methane emission monitoring.
