Abstract:

The method of measuring low absolute pressures by using a single-capillary compression manometer differs in that, to increase accuracy and exclude random errors, mercury flows to the measuring capillary entrance and gradually rises in the capillary without the measuring volume contacting the vacuum system in which pressure is determined, with the calculations being made from different relations of the mercury-level values introduced into a known formula for pressure determination in a single-capillary compression manometer.
