Every Cirris tester that leaves our factory is calibrated in compliance with ANSI/NCSL Z540-1-1994 and ISO-10012 to standards traceable to the NIST in the United States.

Verify Calibration with Performance Check Kits

Cirris provides Performance Check Kits for you to verify that your tester is still calibrated correctly. These kits are simple enough to be used in-house, saving you time and money. Each kit comes with a Certificate of Calibration that validates your Performance Check Kit for a service period of two years.  Learn more here.


Is your tester failing the Performance Check Kit?

In the unlikely event that a Cirris tester is found to be out of calibration, the tester can be sent back to a Cirris facility  or to a third party calibration lab for evaluation and recalibration. This procedure validates your tester for a service period of one year. Find out more here.
