The measurement of airflow velocity and the correct calculation of volume flow at ventilation outlets can present a challenge. The turbulence created there plus differing flow directions make correct measurement more difficult. Air turbulence is particularly strong at swirl outlets, which makes even higher measuring inaccuracies likely.
Get the Testo 417 vane anemometer with integrated 100 mm vane now, in a set that includes two measurement funnels, a volume flow straightener, and other accessories. This ideally equips you to carry out volume flow measurements at plate outlets, ventilation grilles, and swirl outlets.
The Testo 417 vane anemometer with a built-in 100 mm impeller simultaneously measures flow rate, volume flow, and temperature. The measuring funnels included in the kit allow accurate measurement of volumetric flow at the ventilation openings. With volumetric flow straighteners, you can achieve extreme accuracy even at vortex outputs. The calculated volumetric flow is displayed directly on the display of the vane anemometer. Alternatively, you can switch to the current temperature reading.
The direction of the flow, i.e. inlet or outlet, is also displayed on the screen. Time and multipoint averaging provide an indicator of mean volumetric flow, flow velocity, and temperature values. The vane anemometer shows the minimum./max. hold values and functions allow the current readings to be retained. The backlit display allows you to take your measurements even in dark environments.
With this kit you’re ready to start: To measure ventilation grilles or vents, simply attach the testo 417 vane anemometer to the testament 417 funnel. You have selected the funnel factor on the anemometer. the propeller, you can start your measurement.
The Testament 417 volumetric flow rectifier can also be used to measure volumetric flow at vortex diffusers. Combined with measuring funnels and flow rectifiers, the Testo 417 vane anemometer delivers impressive accuracy, despite strong air turbulence at the rotating outputs.
This set includes the testo 417 vane anemometer, testament 417 volume flow straightener, and testament 417 measuring funnel – one for plate outlet (200 mm diameter) and one for ventilation grilles (330 x 330mm). After measuring, you can safely store or transport the device in the bag.
