Duct Blaster Field Calibration Plate

Field Calibration Plate for Minneapolis Duct Blaster 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 allows you to quickly check the calibration of the entire Duct Blaster System with DG-700 gauge.
> The calibration plate, which contains a 5 inch diameter hole, is mounted on the square transition piece that is connected to the end of the flex duct.
> The Duct Blaster fan is turned on to pull air through the calibration plate and simulate a duct leakage test.
> Results from the simulated test are compared to the known leakage rate to determine if the entire system is within a +/- 3% accuracy range.
> Can be used to document calibration compliance for testing programs such as California Title 24 and RESNET Home Energy Ratings.
