testo 417 Vane Anemometer with Funnel Set and Flow Straightener
With this set, you are ready to get started: for measurement at ventilation grilles or plate outlets, simply attach the testo 417 vane anemometer to the testovent 417 measurement funnel. Once you have selected the measurement funnel factor on the vane anemometer, you can start your measurement.
The testovent 417 volume flow straightener can also be used for measuring the volume flow at swirl outlets. In combination with the measurement funnels and flow straightener, the testo 417 vane anemometer offers impressively high precision, in spite of the massive air turbulence at swirl outlets.
The set comprises the testo 417 vane anemometer, the testovent 417 volume flow straightener and the testovent 417 measurement funnels – one for plate outlets (diameter 200 mm) and one for ventilation grilles (330 x 330 mm). After the measurement, you can safely store or transport the equipment in the bag.
