TDLAS200B
The TDLAS201 laser gas telemetry module utilizes laser absorption spectroscopy technology. It emits a specific wavelength laser beam to detect target gas presence within the optical path range, accurately measuring gas concentration.
Molecular absorption spectrum: Methane molecules absorb light at specific wavelengths.
Beer-Lambert's law: Light absorption by methane gas is proportional to gas thickness and concentration.
This technology uses wavelength-specific laser beams to measure methane concentration through light attenuation analysis, with unique methane selectivity. Multiple reflection detection cells enhance sensitivity by allowing repeated laser passes through the measured gas.
