Ultra-precise, selective gas measurement

Providing the most reliable and cost-effective solution for carbon credit verification and GHG reporting, the FAU-TDL is driven by NASA research. A laser produces a specific wavelength of light, tuned to an absorption line: the known light frequency of the target gas. The result is unbeatable response speed and selective gas measurement.
