GT-TS01A Laser Methane Sensor-Shanghai Sangbay Sensor Technology Co.,Ltd.-Shanghai Sangbay Sensor Technology Co., Ltd.

Product Overview

The GT-TSO1A laser methane sensor is developed based on Tunable Semiconductor Laser Absorption Spectrum (TDLAS) technology. It uses a 1653.7nm DFB laser to detect the characteristic "fingerprint spectrum" absorption of methane gas, resisting interference from water vapor or other gases. It adopts a compact multi-reflection optical path structure design, resulting in a long absorption optical path and high detection sensitivity and accuracy. It selects laser and photodetector devices with excellent high and low temperature performance and employs wide-temperature compensation and pressure compensation algorithms, making it highly adaptable to various environments. It adopts a standard threaded mounting interface and a standard communication interface design, making it highly versatile.
