The compact vane anemometer testo 417 in a kit incl. two measurement funnels was developed to make it as easy as possible for you to take measurements on air inlets and outlets as well as plate outlets of air conditioning and ventilation systems. The integrated 100 mm vane quickly ensures precise results. Time and point average values as well as the volume flow are automatically calculated in the instrument and shown on the display. This allows balanced residential ventilation systems to be adjusted particularly efficiently - including quick documentation with the testo Smart App. In addition, the App not only supports you in configuring the measuring instrument and takes over display, storage and documentation of the measured values – it also turns your smartphone into a second display. The testo 417 Kit 1 includes two measuring funnels for plate outlets and ventilation grilles. These can be easily attached to the vane, covering a wide range of outlet sizes and formats.

The compact 100 mm vane anemometer testo 417 is the ideal solution for simple, fast and precise determination of flow velocity and volume flow at air intake and outlet vents of air conditioning and ventilation systems. Adjustment for balanced residential ventilation or measurement at swirl outlets is also child's play with the testo 417 kits including funnel and flow straightener. Thanks to the connection to the testo Smart App, configuration, display (also as second screen) and storage as well as documentation of the measured values are dealt with quickly and without any complications.

Testo is the only manufacturer providing a solution the problem of measuring equally easily and accurately at swirl outlets. The innovative volume flow straightener testovent 417 supports you perfectly in flow velocity measurement at swirl outlets. The volume flow straightener allows redirection of the swirling flow to an almost uniform flow which can then be reliably recorded with a vane anemometer or vane probes. Measurements at swirl outlets without the volume flow straightener lead to lower or higher measurement results, depending on the flow direction in which the swirl impacts onto the vane. The volume flow straightener is used in combination with the optional measurement funnel testovent 417 and the optional vane anemometer testo 417 or the vane probes (Ø 100mm) of testo 435 and testo 480.

The testovent 417 volume flow rectifier is ideal for precise measurements with the testo 417 (0554 4170) or 100 mm vane wheel measuring probes (0635 9435, 0635 9343 and 0635 9340).
