Abstract
An apparatus for determining the explosion limits of flammable gases having a combustion chamber, a conduit leading to the combustion chamber for conveying the sample stream of gas, a temperature control for maintaining the gas in the combustion chamber at a predetermined temperature and an ignition system for igniting the gas. The ignition system includes an exploding wire powered by a low internal resistance battery, thus enabling the testing of corrosive, flammable gases.
