Calibration System

Where accuracy and repeatability of vacuum pressure are essential

The systems are supplied with a vacuum chamber attached, and are equipped with two reference pressure gauges, shown here with Barocel 7025 capacitance manometer gauges from the Edwards Barocel 7000 series.

The calibration system has been designed for use in a wide range of applications where accuracy and repeatability of vacuum measurement is an important aspect of the quality process, and to safeguard the process stability and product quality.

Calibration system ECAL1 provides output comparison between reference gauges and test gauges for a pressure measurement range from 1000 to 10-4 mbar. The user must define the acceptable tolerance between reference gauges and the test gauges, whilst taking into consideration the uncertainty of different calibration process conditions. Note that no adjustments are to be performed on the test gauges during the calibration procedure.

Calibration System ECAL1

The Edwards calibration system ECAL1 is a fully automatic pumping system based on the Edwards T-station 85H turbomolecular pumping station.
