Volume flow measurement with a large Ø 100 mm vane at
duct outlet
Monitoring ingoing air in a disc outlet
Monitors outgoing air in an on-wall ventilator
The compact testo 417
anemometer with built-in
flow/temperature vane Ø 100
mm to measure flow speed,
volume flow and temperature.
Volume flow is shown directly in
the display. Accurate volume flow
calculation thanks to easy input
of duct area. 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, flow speed
and temperature readings.
The optional funnel set facilitates
efficient measurements at
ventilator grilles and disc outlets.
Min/max values can also be
shown in the display. Current
readings can be frozen in the
display using the Hold function.
