Conclusions

  1. 1.

    Precision measurements of low absolute pressures (10−3 to 10−5 mm Hg) should be made by means of mercury compression manometers of a design shown in Fig. 2, and an operation represented by Eq. (6).

     
  2. 2.

    Corrections Δi and Δ2 comprised in (6) should be used in precision measurements and calculated according to the suggested technique.

     
  3. 3.

    The accuracy of measurements can be raised at the lower end of the compression manometer scale by using the repeated measurement technique, which lowers random errors to values not exceeding one percent of the measured pressure.
