manometer allows you to determine the pressure of a gas sample by using the atmospheric pressure and difference in the height of mercury. 

The Manometer

What is a manometer? How does it measure the pressure of a sample of gas?
A sealed-tube manometer (as shown below) can be used to measure pressures below atmospheric pressure. The tube above the mercury is evacuated.
