Australian Pressure Laboratory has developed a Vacuum Comparison System (VCS) for calibration of vacuum gauges down to 0.1 Pa absolute (0.001 mbar, 0.75 mTorr).  Our VCS has been designed and manufactured to meet the requirements of ISO 3567 (calibration of vacuum gauges by direct comparison) including a stainless steel vacuum chamber, turbo-molecular vacuum pump, and range of high accuracy capacitive diaphragm gauges calibrated by NMI Australia.  This is a new service from APL and is not yet within our NATA scope of accreditation, but provides traceability to the International System of Units (SI).
