When choosing a pressure calibrator, you have a number of choices to consider. On the one hand, you can look for a dedicated pressure calibrator such as the Fluke 717 or Fluke 718 - each of these has either a 30PSI or 100PSI built-in pump and works with additional Fluke pressure modules.

Alternatively, you can look for a multifunction calibrator such as the Fluke 725, Fluke 726 that will calibrate pressure, temperature, mA (for 4-20mA), 10VDC and meet a range of calibration needs. (These multifunction calibrators also work with Fluke pressure modules.)
