Aer Sampling offers inspection/calibration service for your critical orifice(s). We recommend you calibrate your critical orifice(s) once every 12 months.
A calibration certificate will be issued:
- The critical orifices are calibrated according to US EPA Method 5 (US CFR Title 40, Part 60, Appendix A, Test Method 5) Section 16.2.2, using a dry gas meter calibrated according to US EPA Method 5, Section 10.3, and other reference instruments with calibrations traceable to the International System of Units (SI).
The standard turnaround time* is 10 working days, beginning the day after we receive both your payment and item(s), in the time zones in which our calibration laboratories are located.
Turnaround time is invalid if item requires repair, and additional time are needed.

At 20 C, 760 mmHg
CMC: Calibration and Measurement Capability Uncertainty. This is the best measurement uncertainty that we can achieve currently. None of our subsequent work can be better (with less uncertainty) than this number.
Your item(s) will be inspected upon receipt to determine if calibration is possible. If your item(s) passes this inspection, it will be added into the calibration queue.
If your item(s) fails this inspection, you will need a Repair Service (PN-772) before the calibration.
