Application
The wheel measuring head 0635 9343 is suitable in conjunction
with testo 480 for flow measurements at ventilation outlets.
Observe the information on the measuring process in the
instrument instruction manual.
Overview
1 Wheel measuring head
2 Handle
3 Direction of flow (flow with testo logo)
4 Connection for plug-in head cable (art. no. 0430 0100)
Where points are hard to access, the probe can be used
with the tripod arm 0554 0743 and probe holder (with or

Adjustment conditions
Adjustment in free jet Ø 350 mm, reference
pressure 1013 hPa, flow to testo logo,
based on testo reference Laser Doppler
Anemometer (LDA).
The digital probe allows measurement values to be
processed directly in the probe. This technology eliminates
instrument measurement uncertainty.
For calibration, the probe alone (without the hand
instrument) can be sent away.
Calculating the determined calibration data in the probe
generates a zero-error display.
