The connection to the testo Smart App enables configuration, display (also as second screen) and storage as well as documentation of the measured values directly the App.With the compact 16 mm vane anemometer testo 416 with telescopic probe and App connection, you can carry out flow measurements the ventilation ducts of air conditioning and ventilation systems easily, quickly and precisely. The integrated telescope can be extended up to 850 mm, making it easier to work overhead or large diameter ducts. To ensure that you have all the relevant information at your fingertips, the testo 416 automatically calculates time and point average values as well as the volume flow rate. And thanks to the compact design and the robust housing, the vane anemometer can also stand it if conditions get a little rougher at times. Configuration of the measuring instrument, display and storage of measured values as well as documentation are all particularly convenient with the testo Smart App. This also turns your smartphone into a second display.
