TESTO VOLUMENSTROM-GLEICHRICHTER
The innovative volumetric flow rectifier testovent 417 from Testo perfectly supports the measurement of the flow at ceiling diffusors. The volumetric flow rectifier changes the swirled flow into a nearly equal flow, which can subsequently be captured reliably with an impeller anemometer or vane probes. The measurement at ceiling diffusers leads to lower or higher results depending on the flow direction. The volumetric flow rectifier can be used in combination with the optional measuring funnel testovent 417 and the optinal impeller anemometer testo 417 or the vane probes (Ø 100 mm) of the testo 435 and testo 480.
