Pressure and Vacuum Calibration Services

The following services are offered by the Pressure and Vacuum Group through NIST Calibration Services. Please contact the technical staff prior to submitting instruments or calibration items for calibration.

Piston Gauge (29010C - 29040S)

This service provides calibrated secondary standard piston gauges, calibrated electronic pressure instruments, and special tests of customer supplied piston gauges. Measurements of pressure are available for submitted calibration items for the range from 10 kPa to 280 MPa. For additional information about our measurements and facilities, see Piston Gauge.

Technical contact: Gregory Driver


Low Pressure Manometry (30010C - 30025C, 30040S)

Measurements of absolute and differential pressure from 0.1 Pa to 360 kPa are made using low pressure manometry. Common pressure instruments calibrated are capacitance diaphragm gauges, quartz bourdon gauges, low pressure gas piston gauges, along with special tests of customer supplied pressure instruments. For additional information about our measurements and facility, see Low Pressure Manometry.

Technical contact: Jay Hendricks


Vacuum Gauge (30029C - 30038C, 30050S)

This service provides calibrated secondary standard ion gauges, spinning rotor gauges, and special tests of customer supplied vacuum gauges. Measurements of pressure are available for submitted calibration items for the range from 10-7 Pa to 30 Pa. For additional information about our measurements and facilities, see Vacuum Gauge.

Technical contact: James Fedchak


Flow/Leak (30060S - 30063 S)

Measurements of helium leaks and low gas flow from 1x10-14 mol/s to 1x10-3 mol/s are made using primary and comparative flow standards. (Contact the Fluid Metrology Group for larger flows from 0.01 mol/s to 6x107mol/s.) For additional information about our measurements and facility, see Flow/Leak.

Technical contacts: Dana Defibaugh or Robert Berg
