Testo® testovent 417 - Funnel set

Measuring air flows and correctly calculating the volume flow at ventilation outlets can be a challenge. The turbulence and different flow directions that occur there make correct measurement difficult. The funnel set, in combination with a vane radanemometer or vane probes, enables simple and accurate flow measurement at ventilation grilles and disc valves. The funnel set testovent 417 is used with the optional vane anemometer testo 417 or the optional vane probes (Ø 100mm) of testo 435 and testo 480. The funnel set consists of two funnels with different dimensions.
