The Q32 Duc-Tester consists of a Duc-Tester module, a DM-2A digital gauge, and a 12-foot flex duct with flanges for mounting on the return register. Specifically designed to measure residential duct leakage, the automated system can measure and locate air leakage in ducts and can measure the results of duct sealing. The system creates 600 cfm, which is five times more flow than necessary to pass California standards, the maker says. Special software for the system ensures accuracy within 2.5%. 604.732.0142. www.retrotec.com.
