Abstract

In 2001 the Centre for Metrology and Accreditation (MIKES) started a project for expanding its absolute pressure range downwards from 0,2 Pa, using two spinning rotor type vacuum gauges (SRGs) as reference standards. The Swedish National Testing and Research Institute (SP) has since many years performed calibrations of low vacuum gauges in the range from 0,0005 Pa to 5 Pa with SRGs. Vaisala Oyj, a well-known Finnish manufacturer of barometers, has a long experience of using SRGs for measuring the reference vacuum of absolute pressure balances in their measurement standards laboratory. The contacts between the three laboratories are traditionally close. Their cooperation consists of the exchange of information, laboratory visits and joint comparisons. A comparison of spinning rotor gauges in 2001-2002 was the latest phase in the co-operation.
