Testo 0554 4173 417 Funnel Set and Flow Straightener

The Testo 0554 4173 is a Funnel Set and Flow Straightener (Funnel Set Testovent 417) that enables a correction of the swirl into a parallel flow from air conditioning outlets. Testo is the only manufacturer to offer a solution for swirl outlets. The Funnel Set Testovent 417 is designed for the measurement on ventilation grilles and disc outlets. However, if the flow rate is measured at swirl outlets the swirl will influence the rotation of the vane anemometer.

• More accurate volume flow measurement independent of the swirl direction
• Reliable measurement results on swirl outlets
• System compatibility with the 100mm vane probes of the testo 435 (0635 9435), 400/445 (0635 9340) and 480 (0635 9343)
