The Wohler DP 700 is an easy to use positive and negative pressure high accuracy air leakage tester which can be used in a wide range of applications. Not only can the instrument be used for the airtightness of duct systems in can also be used for testing enclosures such as air handling units, climatic chambers, vehicles, and electrical cabinets.
The DP 700 has been especially designed for leakage tests according to EN 12599 - Test procedures and measurement methods to hand over air conditioning, and ventilation systems according to EN 14134 - Performance testing and installation checks of residential ventilation systems. The air tightness values are to the classes of EN 13779 (identical to EN 12237, 1507, 15727, 13403, 1751 and 13180).
- The ideal tool for the QA testing of ducts including systems such as those built into residential dwellings
- Additional adapters for air flow rates < 0.3 l/s with a high level of measurement accuracy.
- Suitable for leakage tests of AHU's
- Easy to operate
- Store up to 100 measurements
- Automatic or manual measurement modes
- Practical size, 2 easy to carry storage cases
The Wöhler DP 700 is not designed for continuous use or for long / extended periods in an attempt to locate leaks within a system.
The Wohler DC series software is not available to purchase or as an optional accessory.
