What is a Pressure Calibration Reference Standard

Pressure Calibration Reference Standard
All pressure measurement devices must be calibrated periodically. Pressure calibration is simply the process of comparing a pressure measurement device (the device under test or DUT) to a reference gauge or reference standard. To ensure the most accurate pressure calibration, the reference standard should be roughly four times more accurate than the device under test. The reference standard then, should be a device with the highest possible level of accuracy.

For many years, deadweight testers were the de facto reference standard for pressure calibration. And though they are still in wide use, many calibration labs have moved away from their dependence on deadweight testers and adopted newer technologies to serve as reference standards for their pressure calibration.

AMETEK STC offers an array of reference standard options for pressure calibration with a variety of accuracy ratings and feature sets. The Crystal XP2i Digital Pressure Gauge is ultra-rugged, intrinsically safe, and the world’s most popular test gauge; Crystal’s HPC40 Series Pressure Calibrator delivers high accuracy measuring pressure, and will also measure current, voltage, or temperature; and the Crystal 30 Series Pressure Calibrator is a wide range digital pressure calibrator that’s portable enough to into your shirt pocket.
