RetroTec 100 CFM Calibration Plate for Q32 Duct Tightness tester

Retrotec’s Field Calibration Plate for duct testing systems gives you an easy, five minute test to verify the accuracy of your duct testing system. Performing this test monthly will allow you to detect calibration problems early and fix them before they become serious.

The field calibration plate is compatible with Retrotec’s Q32 and R31 duct testing systems. The field calibration plate is completely compatible with the Minneapolis DuctBlaster. The depressurization test is the same as the pressurization test, except the flex-duct is mounted on the Duc-tester inlet. If the measured flow of your Duc-tester is less than 97 CFM or greater than 106 CFM, our problems checklist will help you to determine a resolution.
