The Rosemount 625IR Fixed Gas Detector provides ultra-fast response times to detect hydrocarbon gases before they can create dangerous situations. Using optical absorption detection technology, the gas detector transmits infrared light through a sapphire lens and reflects light back again to determine gas concentration. Available with a range of options and accessories to improve accuracy inside ducts, provide greater installation flexibility, protect from environmental impacts and more.
