Original 1921 electrical trade vintage magazine ad for the UEHLING INSTRUMENT COMPANY. Main office was located in the Empire Building (at 71 Broadway, corner of Rector Street), New York, NY.

Manufacturers of CO2 Recorders.

The Southern California Edison Company derives the bulk of its power from its hydro-electric stations, but it also maintains a sizable and efficient standby station which is used to full extent during periods of water shortage.

Since this plant is called on to carry appreciable loads for indefinite periods, it's operating expense must approach as nearly as possible that of the Hydro stations. This calls for high operating efficiency. And it is one of the reasons that this company uses 60 Uehling CO2 Recorders to point the way to greatest savings in fuel oil.

Central Station executives who are seeking methods to increase plant efficiency and to cut down operating costs can well afford to follow the example of some of the country's largest modern stations which are using Uehling CO2 equipment to lead the way to appreciable fuel savings.
