MIC-200-TDL Open-circuit laser methane gas detector

The open-circuit laser methane gas detector is an instrument that uses the absorption characteristics of methane gas in the near-infrared spectrum. Based on the advanced open tunable semiconductor laser absorption spectroscopy technology (TDL AS), the main principle is to detect the gas concentration in an open space area through the absorption of a specific wavelength of light by the gas, and the detection distance can reach 120 Meter.
