Pressure Calibration Services

Pressure calibration refers to the amount of force applied by a fluid to a surface and is typically measured in the amount of force per unit of the surface area. Pressure measurements are typically expressed in psi, which stands for pounds per square inch, but can be stated in bar, inHg., or inH2O.

During pressure calibration, the unit under test is compared to a calibrated pressure measurement master. The calibration is meant to ensure that the pressure gage, recorder, or transducer being calibrated produces the same reading as the pressure measurement master.

The calibration is repeated at different pressures to ensure that accurate measurements are consistently produced. If the unit under test produces a different output than that produced by the master, it must be adjusted to match. This calibration must then be performed at every level of pressure to ensure that the results remain consistently accurate.
