Vacuum Calibration

Barometer, Vacuum Gauge Calibration and More

The calibration lab at Laboratory Testing Inc., known as LTI Metrology, is a supplier of vacuum calibration services near Philadelphia PA. Our highly trained technicians perform vacuum calibration on various types of instruments including vacuum gauge calibration for absolute pressure, atmospheric pressure, and gage pressure instruments. Vacuum transducer calibration and barometer calibration are also offered with the capabilities listed below.

  • Barometer Calibration
    • Aneroid
  • Vacuum Gage Calibration (0-30″ Hg; 2% to 0.1%)
    • Absolute Pressure
    • Atmospheric Pressure
    • Gage Pressure
  • Vacuum Transducer Calibration (to less than 0.1%)

Vacuum calibration customers receive a detailed Calibration Certificate for each item calibrated that lists:

  • Complete calibration results
  • Our NIST-traceable standards
  • Information on any adjustments or repairs made during calibration

The Vacuum Calibration Process

Computerized pressure modules with negative pressure capacities are utilized to perform the inspection and record the results of vacuum calibration. Before the process begins, instruments are exercised to full capacity three times to be sure they are in working order.

During the vacuum calibration process, a known standard is set to each pressure point that is inspected and compared with the readings received from the instrument being calibrated. This identifies any deviation from the standard. Instruments typically receive a 5 point vacuum calibration with comparisons to the standard occurring at every 20 percent of capacity. A higher accuracy calibration will include 10 inspection points at every 10 percent of capacity.
