Trust the Expertise of InnoCalExample of InnoCal's industry leading certificates

InnoCal maintains some of the most accurate NIST-traceable standards in the country for calibrating flow rates of almost any gas. Our huge fleet of flow calibrators in our ISO17025 accredited lab (A2LA cert 1746.01) means shorter lead times than the competition. InnoCal’s flow technicians go through extensive training on air flow calibration from industry leaders like DH Instruments to ensure you can trust the measurements.

We can verify the accuracy of your flowmeter or plot the flow rate of your rotameter. If you need specific test points or gases to accommodate your requirements, we will do that at no extra charge. Plus if you have specialty flowmeters, we can engage an approved vendor to ensure the same levels of quality you have come to expect.
