The Cenco Beta Ray H/C Meter Is manufactured by Central Scientific Company under license by Standard Oil Company (Indiana).
H O W IT OPERATES To make the hydrogen test, a sample of the liquid hydrocarbon is poured into a cell within the apparatus. The beta ray source is made to radiate equally in two directions, each going to a separate detector. One passes through a fixed absorber, and the other through an absorber that can be moved and also through the sample. The movable absorber is shifted until a galvanometer shows equal currents are being produced by the two radiations. Then, by reading the position of the absorber the necessary data is quickly obtained. Write today
