LGD Compact Ultra CH4 is a laser based methane sensor with fully integrated electronics, designed for compact leak detection systems. The sensor maintains the mechanical footprint of previous LGD Compact generations while reducing external cabling and integration effort. An optional Ultra+ variant enables improved methane detection stability at low concentration levels.
