Product Descriptions: 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 pre-calibration over full temperature enable long-term stability in hazardous conditions and complex gas environments. It has been widely deployed for industrial process monitoring and control, environmental sensing, plant and infrastructure security such as underground pipe networks. Features • 0~100% LEL measurement range (customizable 0~100%vol) • Super high accuracy over full temperature range • Fast response T90<25s • Super stable performance at high humility environment • TDLAS technique drive high methane selectivity • Low power consumption • modularized design for ease integration Specifications • Working principle: Tunable Diode Laser Absorption Spectroscopy (TDLAS) • Measurement range: 0~100% LEL • Accuracy: 0 ~ 20%LEL ±1%LEL;20~ 60%LEL ±3%LEL;60~ 100%LEL ±5%LEL • Resolution: 1% LEL • Response time: T90 < 20s (Diffusion mode) • Warm-up: <25s • Working temperature: -25 ~ 55℃ • Working humidity: 0~98%RH • Working voltage: 3.2V~5.5V • Working current : ≤50mA,Max 150mA • Digital signal format :TTL(3.3V) • IP grade: IP66 • Dimension: 35mm*60mm (diameter*length)
