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. LTI Metrology performs pressure calibration to 40,000 PSI, including barometer calibration, manometer and pressure transducer calibration, dead weight tester and pressure gauge calibration.

With every pressure calibration we perform, our customers receive a Calibration Certificate with all the information they need, including:

  • Instrument condition
  • NIST traceability
  • A2LA accreditation to ISO/IEC 17025
  • Calibration results
  • Repairs and adjustments, if applicable

Working with reliable instruments is essential for efficiency, quality and safety. Let our lab keep all your instruments in top condition, including:

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.

More Than Calibration

LTI Metrology is the calibration lab at Laboratory Testing Inc., located in Hatfield, Pennsylvania (USA) just outside of the Philadelphia, PA area. Expedited service is available when you need your calibration results quicker than our standard turnaround. For convenience, we can arrange order pick-up and delivery services for customers local to our facility.

Pressure calibration is just one of the many calibration services provided by our one-stop calibration laboratory. For a detailed look at our calibration capabilities, refer to our list of Calibration Services & Instruments Calibrated under Resources.

Our Customers Say:

“I wanted to write and applaud LTI for assisting us in calibrating some new equipment, while re-calibrating equipment that was moved. We did not have enough advance notice to schedule LTI to come in and complete the calibration / re-calibration of some of our equipment. As a result, LTI did what they could to get us out of a jam and reduce the one to two week turnaround down to two days. I wanted to let LTI know that this was very much appreciated and we value the service your organization gives us.“
