Abstract

1338870 Measuring ethanol content electrically VYSOKA SKOLA CHEMICKO-TECHNOLOGICKA 5 June 1972 26178/72 Heading G1N Apparatus for determining ethanol content of exhaled breath comprises a duct 1 with non- return valves 2, 9 at inlet and outlet respectively, and two measuring cells 3, 4, each containing a catalyst device 5, 7 respectively for the catalytic burning of ethanol and a non-catalytic device, 6, 8, respectively for the measurement of the heat produced by the burning. The devices are arranged in a Wheatstone bridge. The tube is provided with a mouth-piece. Each cell includes a chamber of porous sintered bronze.
