Duct Leakage Testing EquipmentSimplicity

The DLT instrumentation and software are easy to use. Results appear as an easy-to-read homeowner report or a more detailed technical report.

Durability

Specially designed for use in the field, the DLT is easily transported, yet its rugged construction is built to last.

Versatility

The DLT can be attached directly to the HVAC system’s central return or be used to measure air flows through handler fans, registers and grills, and exhaust fans. The software will automatically detect if the fan is setup for pressurization or depressurization, post the mode on the screen and perform appropriate calculations.

Reliability

Guessing is no longer an option. The DLT gives quick and accurate air-tightness measurements from 15 to 650 CFM, allowing you to demonstrate duct-leakage problems and estimate efficiency losses.
