Calibration Orifice Set
Calibration Orifice Set
U.S. EPA allows critical orifices to be used as calibration standards. This mether calibration set is used for calibrating dry gas meters in order to perform post-test calibration audits. The orifice calibration set contains five of our critical orifices with 1/2″ quick connects and software. Re-calibration recommended annually. Calibration Orifice Set, 6 Calibrated Critical Orifices. and Spreadsheet CD (or thumb drive) for Method 5.
