With advanced Tunable Diode Laser Absorption Spectroscopy TDLAS technology and optimal compact package design, Gasboard-2501 TDLAS methane detector achieves high precision and stability, high gas selectivity, and humidity interference-free, specially designed for LEL-level safety alarm in harsh environments.
Cubic Sensor Gasboard-2501 TDLAS Gas Analyzer is developed based on Tunable Laser Absorption Spectroscopy (TDLAS) technology. Adopting a narrow-band tunable laser source, special gas chambers and optical path design, Gasboard-2501 TDLAS CH4 gas sensor achieves characteristics of high precision, enhanced fast response, humidity interference-free, low maintenance and long lifetime.
Based on the temperature compensation algorithm and self-diagnosis function, Gasboard-2501 ensures stable performance even in harsh working conditions and complex environments. Due to its modular structure, it is easy to be integrated into a fixed detector that can be applied in the fields of oil and gas, landfill and industrial scenarios.
