Kenotometer (Early 20th century)

A kenotometer, such as this, is a device used in steam turbines which are operated at pressures below atmospheric pressure (in a vacuum condition). It measures pressures approaching a perfect vacuum. The absolute pressure is indicated by a mercury column, usually expressed in inches of mercury. This device was most likely salvaged from a small municipal or private diesel power station. Following the Electrification Act of 1949, SaskPower began to integrate communities to the expanding provincial power grid. Once a community was incorporated, SaskPower would acquire and subsequently decommission the local power station.
