Peace-of-mind backflow test kit calibration

We want to make sure your test kit are DEAD ON ACCURATE so you can be sure it performs reliably in the field. As a backflow prevention device tester, you be required to calibrate your differential pressure gauge at least once a year or according to the requirements of the competent authority. In Canada, section 7.2 of B64.10.1-11 applies: ” Test kits shall be verified or calibrated for accuracy at least annually or as required by the regulatory authority.”

Shortly before the expiry date of your calibration report, we will remind you that your differential pressure gauge must soon be verified.
