With advanced Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology and optimal compact package design, Gasboard-2501 achieves high precision and stability, high gas selectivity, and humidity interference-free, specially designed for LEL-level safety alarm in harsh environments.

Overview of TDLAS LEL-Level Methane Sensor Gasboard-2501
Gasboard-2501 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 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.

Features
Narrow absorbing spectrum determines unique selectivity for methane
Laser technology to ensure superior accuracy with super low drift
Laser principle to ensure anti-humidity
Extended cable with connector for better integration
Long lifetime over 10 years
