Digital differential pressure gauge with two independent pressure sensors. Operates with the Minneapolis Blower Door and Duct Blaster systems to display air flow readings. Pressure range is 0 to 1,250 Pascals (0 to 5 in H2O) bidirectional. Accuracy is +/- 1% of pressure reading, or 0.15 Pascal, whichever is greater.
This is the successor to the DG-3 and has been updated to the DG-1000.
