Laser gas detection (LGD) is based on TDLAS technology: Laser beams scan across absorption lines of target gases, enabling high-resolution absorption measurement. This technology has unique advantages: Precise optical, non-contact measurements, excellent selectivity of target gases and detectivity in the sub-ppm range.
