The Testo 416 (0560 4160) Anemometer with Attached Telescopic Vane Probe is a compact anemometer with a fixed vane probe. The 416 is particularly suitable for flow velocity measurements in ducts thanks to the extendable telescope (max. length 890 mm, diameter 16 mm). The volume flow is directly shown in the display. For volume flow calculation purposes, the duct cross-section area can be conveniently entered into the testo 416. The timed and point mean value calculations provide information on the average volume flow. The Hold function allows the current measurement value to be fixed in the display. Min./max. values are also displayed at the press of a button. The optional TopSafe reliably protects the instrument from dirt and impact, ensuring a particularly long working life.
