The TD11 laser methane sensor is a high-precision, miniaturized gas sensor based on Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology. It features excellent selectivity, compact size, low power consumption, stable performance, a long service life, and high sensitivity. Easy to use and capable of directly replacing sensors based on NDIR (infrared) or catalytic combustion technologies, it is widely used in environments where combustible or explosive gases may be present.
