Calibration Orifice Set
Calibration Orifice Set
U.S. EPA allows critical orifices to be used as calibration standards. The orifice calibration set contains five of our critical orifices with 1/2″ quick connects and software. Re-calibration recommended annually. Calibration Orifice Set, 5 Calibrated Critical Orifices and Spreadsheet CD (or thumb drive) for Method 5.
