Pressure Measurement

Introduction to Pressure Measurement

 

Vacuum pressure measurement is broadly divided into two categories: high and low vacuum. Many of the different techniques used to measure these categories have an overlap at some point in the pressure range. By combining several different types of gauge it is possible measure system pressure from 10 mbar down to 10-11 mbar.

For measuring in the low vacuum range (30 mbar to 10-3 mbar) we offer a range of Pirani gauges; for pressures below this (10-3 mbar to 10-11  mbar) we offer a range of ionisation gauges.

VG Scienta offers both types of gauges in various options, along with a high performance gauge controller. However, for the user who requires a more basic configuration, a low cost alternative gauge and controller is available. This offers vacuum pressure measurement in the range 1000 mbar to 10-10 mbar.
