Overview
Gasboard-2502 is a multi-pass TDLAS sensor for low-level methane leaks in ambient air, with a 1 ppm detection limit, 0.1 ppm resolution, 0-1000 ppm range and warm-up under 10 seconds. Self-diagnosis, smart power management and a 10+ year life suit fixed detectors for oil and gas methane emission monitoring.
Key Features
- Super low concentration range 0~1000ppm
- High accuracy and sensitivity to methane gas
- Superior anti-cross interference compared with semiconductor technology
- Fast response to capture minor gas leakage
- Smart power consumption design
- Long lifespan over 10 years
