I'm in search of a Retrotech duct Tester?
I have one that I bought several years ago and it has never been used. Would be willing to sell it. Doesn't have the new DM32 gauge, but it does have the DM-2 gauge. As stated, it was brand new in 2010 when I bought it and have never used it. We have 3 Minneapolis set-ups and have only used those. If you are interested, email is the best way: email@example.com
