Vane Anemometer with Measurement Funnels (Part # 0563 1417)
The compact testo 417 4 inch vane anemometer was developed to ensure precise results when measuring air inlets and outlets of air conditioning and ventilation systems. 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 commercial and residential ventilation systems to be adjusted especially 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.
