Description
User-Friendly and Accurate
Designed with user convenience in mind, the DALT 6900 offers a straightforward, step-by-step duct leakage test configuration. It automates the testing process based on the standards set out in the SMACNA HVAC Air Duct Leakage Test Manual, ensuring accuracy to ±2.5% of reading. This precision is critical for meeting industry standards and ensuring system integrity.
Portable and Efficient Design
Despite its robust construction and powerful onboard motor, the DALT 6900 is remarkably portable. It is equipped with pneumatic tires, facilitating easy transport across job sites while leaving a minimal footprint. This feature is especially beneficial for contractors working in various locations.
Intuitive Full Color HD Touch Screen Display
The device boasts an easy-to-follow, full color HD touch screen display. This interface guides the user through the ductwork leakage testing process, offering multiple choice configuration options for a tailored testing experience. The touch screen also allows for quick switching between measurement unit outputs, including Fahrenheit, Celsius, m³/s, CFM, l/s, and m³/h, enhancing its versatility.
Simplified Operation Without Orifice Plates
One of the standout features of the DALT 6900 is its elimination of the need for orifice plates. This design choice not only reduces the time required for testing but also minimizes potential errors. All necessary parts for the leakage tests are included with the unit, eliminating the need for additional research or orders for different projects.
Versatile Testing Options
The DALT 6900 is capable of performing both positive and negative (decay) pressure tests. This versatility is achieved through a simple rearrangement of the hose, saving time for contractors handling diverse test requirements.
