UV Sensing Technology

UV spectroscopy is an optical remote sensing method that detects gases by their direct interaction with characteristic light frequencies in the UV region. The primary strengths of this technique are it’s long-path capabilities, simplicity, versatility, speed, accuracy, and cost-effectiveness

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
