UEi Test Instruments designed the CD100A Combustible Gas Leak Detectorto 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� flexible hose and a tip-based worklight 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.
