This instrument is used in steam turbine condensers which are operated at pressures below atmospheric pressure.           (In a vacuum condition).

It measures pressures approaching a perfect vacuum.               (0 pressure absolute).

The absolute pressure is indicated by a mercury column, usually expressed in inches of mercury.

This Instrument measures the very low Absolute pressure in the condenser.

Hours of operation 2023

We are located on the grounds of the Leduc West Antique Museum. Travel 5 miles west of Leduc on Highway 39. Go north on Range Road 260 (Cohne Dale Road) for about 800 metres and the museum will be on your right. The LWAS Annual Exposition on July 22 & 23 was a great success and now we look forward to the Fall Harvest on September 9 & 10, with public tours, exhibits and the Tractor Pull Provincial Finals event. The final music performance of the season will feature “Celtera” and as their name implies is steeped in the music from the Emerald Isle and Scotland. Finally, on September 15 & 16, the Lesco Pro Truck Show n' Shine arrives at Leduc West. Although our museum will only be open on the 16th, please come out and see the trucks on both days!
