TDLAS CH4 Sensor Gasboard-2501 Series
Introduction
Gasboard-2501 methane sensor is high-performance gas sensor based on tunable laser absorption spectroscopy technology (TDLAS).
Adopting a narrow-band tunable laser source, special gas chambers and optical path design, Gasboard-2501 TDLAS CH4 sensor has features of great stability, high precision, enhanced fast response, humidity interference-free, low maintenance and long lifetime.
Gasboard-2501 series could measure CH4 up to 100%Vol, are designed for scenarios with harsh working conditions. Suitable applications include Oil & Gas industry, energy sector, landfill monitoring, LNG transportation, gas leak detection, emission quantification, etc.
Features
1.Narrow absorbing spectrum determines great selectivity to CH4
2.Laser technology to ensure superior accuracy with low drift
3.Great anti-cross interference to other gases and high humidity
4.Fast response time
5.Low power consumption
6.Long lifetime of 10 years
