Volume flow measurement
Automatic calculation of volume flow in ducts
and at outlets simply by inputting the duct
parameters and measuring the flow velocity.
Funnel volume flow measurement
Pitot tube volume flow
measurement
Simplified volume flow measurement at the air
outlet with a Testo measurement funnel.
K-factor volume flow measurement
Calculation of volume flow using K-factor and
differential pressure measurement.
Calculation of volume flow using measurement
of differential pressure and Pitot tube factor.
Recommended in the case of high flow
velocities or heavily contaminated flow.
The intuitive measurement menus:
suitable for any application.
