Once you know which categories of instruments will meet your measurement uncertainty needs and will operate in your environment, you can determine which models in those categories can be used to calibrate your pressure devices, based on pressure measurement mode (absolute, gauge, differential), test medium (gas, oil, water…) and pressure measurement range.
| Pressure mode and test medium | Calibration standards typically used | Pressure range covered by calibration standards |
| Absolute pressure (relative to vacuum) i.e. barometers, altimeters, vacuum sensors, capacitance diaphragm gauges, depth sensors Gas medium, unless otherwise noted | FPG8601 force-balance piston gauge | 0.001 to 2.2 psi (5 Pa to 15 kPa) |
| PG7601 and 2465 absolute piston gauges | 0.2 to 1000 psi (1.5 kPa to 7 MPa) | |

| * PG7102, PG7202 and 2470 piston gauges | 0.2 to 15k psi (1.5 kPa to 100 MPa) | |
