The MH-TD12 laser methane gas sensor is a high-precision, miniaturized 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, it serves as a direct replacement for sensors based on NDIR (Non-Dispersive Infrared) or catalytic combustion technologies and is widely used in environments where combustible or explosive gases may be present.
