Results of comparisons of standard instruments that are components of the state standard of the unit of pressure for the region of variable pressures (GET 131–81) are presented. The reliability of the results of comparisons of the instruments with the declared uncertainties and the reproducibility of the unit of pressure are demonstrated.
