UV spectroscopy is an optical remote sensing method that detects gases by their direct interaction with characteristic light frequencies in the UV region.

UV-based gas detection systems have the ability to sense more than one gas at a time, allowing customers to create dual-layered fencelines of detection or a double duty in-situ configuration. Much like their cousins of IR-based gas detection, these systems can provide practically instant data readings to a PLC or DCS, which affords control systems managers plenty of time to make system critical decisions for the safety of onsite an offsite populations.
