In the context of climate change, methane is becoming increasingly significant because it has a greenhouse potential many times higher than carbon dioxide. The Axetris LGD Compact-A CH4 laser gas detection OEM module detects methane down to the sub-ppm range. And due to the LGD Compact's small-volume multipass cell, real-time measurements are possible. The robust and compact design allows both easy integration and mobile use for a wide range of methane measurement applications.
