Pressure Calibration

Barometer, Manometer, Pressure Gage Calibration and More

Pressure gauge calibrationRoutine pressure calibration will help ensure the accuracy and precision of your pressure instruments. The use of reliable instruments is essential for efficiency, quality and safety. LTI Metrology, the calibration lab at Laboratory Testing Inc., performs pressure calibration to 40,000 PSI. These services include barometer calibration, manometer, pressure transducer calibration, dead weight tester and pressure gage calibration (pressure gauge calibration).

With every pressure calibration we perform, our customers receive a Calibration Certificate with all the information they need about the condition of their instrument, calibration results, NIST traceability, our A2LA accreditation to ISO/IEC 17025, and repairs and adjustments.

The Pressure Calibration Process

Computerized pressure modules with capacities from vacuum to 40,000 PSI are used to perform pressure calibration and record the readings. Based on the measurement range of the instrument undergoing calibration, one of LTI’s six pressure modules will be selected for the inspection. It is customary to exercise the instrument to its full capacity three times before beginning calibration. As with most calibrations, a standard with a known value or capacity is compared to the instrument being calibrated during the pressure calibration process. Most instruments undergo a 5 point pressure calibration, whereby the inspection occurs at every 20 percent of capacity. A higher accuracy pressure transducer or pressure gage calibration will include 10 inspection points at every 10 percent of capacity.
