SYCHA-3AB Laser Methane Sensor CH4 Gas For Testing

Product Description

SYCHA-3AB laser methane gas sensor is a high-precision, miniaturized high-concentration gas sensor designed based on tunable laser absorption spectroscopy (TDLAS) technology. It has the characteristics of small size, low power consumption, stable performance, long sensor component life and high sensitivity. It can continuously detect methane concentration in air and transmit relevant data in real time. At the same time, the sensor also has the function of internal temperature and pressure detection.
