Abstract
Primary vacuum systems of the Electrotechnical Laboratory (ETL) and th e Istituto di Metrologia ''G. Colonnetti'' (IMGC) were compared in the pressure range 10(-4) Pa to 10 Pa by using spinning rotors as transfe r gauges. Several rotors were calibrated at both laboratories in an ar gon atmosphere. The results obtained are in good agreement and are wit hin the uncertainty values of both the laboratories.
