The KACISE TDLAS200 High-Sensitivity Laser Methane Sensor is designed for precise methane detection with unparalleled accuracy. Utilizing Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology, it offers a detection range of 0~5000ppm and a static detection limit of 0.5ppm. Its high sensitivity ensures reliable performance in various environments, with an operating temperature range of -20~50℃. The sensor features a built-in reference cell for automatic calibration and a compact design for easy integration. KACISE combines advanced technology and durability, making this sensor ideal for industrial safety and environmental monitoring.

"Methane molecules absorb light of a specific wavelength" --Molecular absorption spectrum
"The amount of light absorbed by a transparent medium (methane gas mass) is proportional to the thickness and concentration of the gas mass" --Beer-Lambert's law

According to the above physical principles, a beam of light of a specific wavelength can be used to penetrate the leaking methane gas mass. According to the degree of weakening of the beam, the concentration of methane in the gas mass can be measured, and it only responds to methane (unique selectivity).

Using a detection cell with multiple reflections and allowing the laser to repeatedly pass through the gas being measured can multiply the detection sensitivity.
