SYCHA-1AA Laser Methane Sensor CH4

Product Description
SYCHA-1AA laser methane gas sensor is a high-precision, miniaturized gas sensor designed based on tunable laser absorption spectroscopy (TDLAS). It has the characteristics of small size, low power consumption, stable performance, sensor components, long life and high sensitivity. It can continuously detect methane concentration in air. The relevant data is transmitted in real time, and the sensor also has the function of internal temperature and pressure detection.
