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.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 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 configuring the measuring instrument and takes over display, storage and documentation of the measured values - it also turns your smartphone into a second display.
