Kanomax has developed the most advanced Duct Air Leakage Tester (DALT) for commercial duct systems. It’s designed to be simple to use, accurate, and extremely convenient. The instrument provides step-by-step duct leakage test configuration and automated leakage testing based on the SMACNA HVAC Air Duct Leakage Test Manual, and is accurate to ±2.5% of reading. Though built tough with an on-board, powerful motor, the DALT 6900 is very easy to transport on its pneumatic tires and leaves little to no footprint on the job site.
The instrument requires very little training due to the easy-to-follow, full color HD touch screen display through which the user can follow the step-by-step ductwork leakage testing process and select from multiple choice configuration options. The touch screen also allows the user to quickly toggle between measurement unit outputs like Fahrenheit and Celsius temperature units to m3/s, CFM, l/s, or m3/h airflow units.
