High Accuracy TDLAS CH4 Sensor Methane Gas Sensor

Product Details

Product Description

Product Description
Introduction
Gasboard-2500 is a methane gas sensor based on self-developed Tunable Diode Laser Absorption Spectroscopy(TDLAS) technology. This technology's high sensitivity and selectivity，as well as our precalibration over full temperature enable long term stability at hazardous conditions and complex gas environment. It has been widely deployed for industrial process monitoring and control, environmental sensing, plant and infrastructure security such as underground pipe network.
Features
1.0~100% LEL measurement range (customizable 0~100%vol)
2.Super high accuracy over full temperature range
3.Fast response T90<25s
4.Super stable performance at high humility environment
5.TDLAS technique drive high methane selectivity
6.Low power consumption
7.Modularized design for ease integration
