Product Description

The compact vane anemometer testo 417 was developed to make it as easy as possible for you to take measurements on air inlets and 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. testo 417 is also available in two practical kits: 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. In addition to the two measuring funnels, the testo 417 Kit 2 includes a volume flow straightener to achieve precise results even at swirl diffusers.
