Testo 417

The Testo 417 vane anemometer has a built-in 100mm diameter flow/temperature vane to measure flow speed, volume flow and temperature. Accurate volume flow calculation due to easy input of duct area is shown directly on the display. In addition, it is easy to switch to the current temperature reading. The flow direction, i.e. drawn in or blowing, is visible in the display. Timed and multi-point mean calculation provide information on mean volume flow. Min/max values can also be shown in the display. The Hold function enables the current reading to be frozen on the display.
