Measuring and application ranges of velocity probes

Thermal anemometers are best
suited for low speed velocities, vane
are utilizzed for the mid-speed
range, while pitot tubes achieve
maximum accuracy in high-speed
air velocity. The appropriate choice
of the right air velocity probe also

depends on the application
temperature. Thermal anemometers,
for example, have only a very limited
operating range. Testo designs and
manufacturers air velocity
instrumetns utilizing all three
measuring technologies. If the

measuring technology that best suits
your application needs is not on
display in this brochure, please call
Testo today to obtain additional
information.

The air velocity range betwen 0 to 20,000 fpm
can be divided into three measuring areas:

- Low-speed velocity 0 to 1000 fpm

- Mid-speed velocity 1000 to 10,000 fpm

- High-speed velocities over 10,000 fpm
