| The first step to selecting the right pressure calibration product is to understand the specifications of the device under test (DUT). Following is a summary of which products are used to calibrate different categories of DUTs, based on total one-year measurement uncertainty specifications (assumes a 4:1 test uncertainty ratio is desired). |

| Total uncertainty specification of the device to be tested | Calibration standards typically used for this application | Typical total 1-yr uncertainty of reference standard |
| ±0.08% and greater Pressure measurement devices: gauges, sensors… | Fluke handheld process calibration tools | 0.025% to 0.25% |
| PPC4E wide-range gas pressure controller/calibrator | 0.02% | |
| E-DWT hydraulic electronic deadweight tester | 0.02% | |
| ±0.03% to 0.075% Medium performance sensors and calibration transfer standards | PPC and 7000 pressure controller/calibrators | 0.008% to 0.015% |
| RPM and 7050 reference pressure monitors | 0.008% to 0.015% | |
| P3000 deadweight testers and M3800 deadweight testers | 0.008% to 0.015% | |
