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.
