Absolute pressure gauges for measuring pressure relative to a perfect vacuum.
Absolute reference pressure gauges are used in applications where a system pressure is not influenced by changes in atmospheric pressure.
Leak testing a component is often carried out using an absolute range pressure gauge, particularly over long periods of time where there is the greater chance of a change in atmospheric pressure.
