A DM32 user in Atlanta, GA asked "On the DM32 smart gauge-why is the DucTester listed under Blower Door devices?" A: The DucTester is listed under Blower Doors because when the DucTester is used to as a blower door it has different flow curves. Notice the icon of the 200/300 do not have a flex duct, this means its being used as a Blower Door. Under Retrotec DucTesters, it's labeled 240/340 and the DucTesters have a flex duct in the icon. |
