Pressure Calibration - UKAS
Pressure Gauge Calibration - Instrument Calibration Services
Our UKAS pressure calibration laboratory is well equipped with a wide range of standards from precision digital barometers to primary sources such as pressure balances or dead weight testers. We can generate and accurately measure pressures from about 0.001mbar right up to 4,000bar with low uncertainties.
This puts the calibration of most types of pressure instrument within our scope, from digital barometers, manometers, industrial pressure gauges and dead weight testers, including instruments with an electrical, frequency or charge output, including Kistler Pressure Sensors.

Gauge, Absolute & Differential Pressure
Gauge pressure is the deviation of a particular pressure away from atmospheric pressure. It can be positive or negative.
Eg. A dial pressure gauge whose pointer reads zero when no pressure is applied would usually measure gauge pressure.
Absolute pressure is a measurement of pressure relative to a complete or absolute vacuum. It will always be positive.
Eg. A barometer measures absolute pressure.
Differential pressure is the measurement of any pressure relative to another pressure. It can be positive or negative.
Eg. A manometer used to measure the pressure drop across an air filter is measuring differential pressure.
