testo 417 is a compact, large-area anemometer with a built-in flow velocity / temperature vane. It measures flow velocity, volume flow and temperature. Thanks to the integrated measurement with the 100 mm vane, it is ideally suited for measurements at air input and output vents. The flow direction, i.e. blowing or sucking flow, is visible in the display. The optimum funnel set additionally allows measurements on ventilation grilles and disc outlets.
The volume flow is directly shown in the display. For the purposes of volume flow calculation, the duct area can be easily entered into the testo 417. In addition to this, the instrument can be switched over to display the current temperature. Timed and point mean value calculation provide information on the average volume flow, flow velocity and temperature measurement value. The Hold function allows the current measurement value to be frozen in the display, min./max. values are also displayed at the press of a button.
