Vane anemometer testo 417 incl. measuring funnel for disc valves, measuring funnel for vent grilles and rectifier

The measuring funnels enable simple and accurate flow measurement on ventilation grilles (330 x 330 mm) and plate outlets (Ø 200 mm).
The flow straightener supports the flow velocity measurement at swirl outlets by changing swirled flow into an almost uniform flow. This uniform flow can then be reliably recorded by the vane anemometer.

Scope of supply: Vane anemometer, measuring funnel for plate outlets, measuring funnel for ventilation grilles, flow straightener, transport bag, calibration protocol, batteries
