Vacuum Calibration

APL sucks, but in the best kind of way – vacuum calibration is one of our specialties.

No Pressure, No Problem

We encounter pressure measurement in everyday life, whether it’s checking their tire pressure or hearing about variations in atmospheric pressure on the evening news. For certain applications, accurately measuring the absence of pressure, or the quality of vacuum, is far more important.

Many advanced manufacturing processes must be performed in a near-perfect vacuum to prevent contamination or reaction with surrounding air. Refrigeration mechanics need to measure the quality of vacuum when evacuating air-conditioning refrigeration lines. These pressures, far below atmospheric pressure, are achieved at APL using our Vacuum Comparison System (VCS) using a turbomolecular pump rotating at 80,000 revolutions-per-minute. Calibration in this area is uniquely challenging and APL is the only NATA commercial laboratory with accredited capability down to 0.0015 Torr (2 x 10-3 mbar).

We can also provide legal traceability to reference standards in this vacuum range, as a Verifying Authority appointed by the Australian Government, National Measurement Institute. This enables us to issue reports under Regulation 13 of the Australian Measurement Act.
