UEi Test Instruments designed the CD100A Combustible Gas Leak Detector to help professional service engineers detect combustible gas leaks in residential and small commercial applications. The semiconductor sensor ensures a rapid response and the adjustable. tic_ rate helps pinpoint the precise location of the leak. The combination of an 18•À_ flexible hose and a tip-based work light make the UEi CD100A especially useful for difficult to access locations. The UEi CD100A includes a protective rubber boot and is easy to use. The UEi CD100A is capable of sensing many combustible non-combustible and toxic gases that include but are not limited to: Acetone Alcohol Ammonia Benzene Butane Ethylene Oxide Gasoline Halon Hydrogen Sulfide Industrial Solvents Jet Fuel Lacquer Thinners Methane Naphtha Natural Gas Propane Refrigerants and Toluene.
