Measuring airflows and calculating volumetric flow rates at ventilation outlets often presents a challenge. The resulting turbulence and varying flow directions make accurate measurement difficult. However, with the testovent 417 funnel set, this task is made simple and precise.

Easy and Accurate Measurements
The testovent 417 funnel set, when used in combination with a vane anemometer or vane probes, allows for easy and accurate flow measurement at ventilation grilles and diffuser valves. The specially designed funnels ensure a uniform flow and minimize turbulence to guarantee precise measurement results.

Versatile Application Options
The testovent 417 funnel set is compatible with the optional vane anemometer testo 417 and the optional vane probes (Ø 100 mm) of the testo 435 and testo 480. This provides versatile application options and adapts to the individual requirements of various measuring devices.

Practical Set with Two Funnels
The set consists of two funnels with different dimensions, enabling precise measurement at various ventilation outlets. With this set, you are well-equipped to conduct accurate flow measurements in different situations.

Optimize your air flow measurements with the testovent 417 funnel set and obtain reliable results for efficient air circulation in your spaces.
