The highly accurate differential pressure meter, testo 521, with an internal pressure sensor
from 0 to 100 hPa is ideal for Pitot tube measurements in the range 5 to 100 m/s.
testo 521 is available in 2 accuracy classes. testo 521-1 with an internal pressure sensor with Class 0.2,
testo 521-2 with an internal pressure sensor with Class 0.1.
Differential pressure meter
| Model | Description |
|---|---|
| 521-1 | Differential Pressure Velocity Meter 0...100 hPa / +-0.2 % fsv |
| 521-2 | Differential Pressure Velocity Meter 0...100 hPa / +-0.1 % fsv |
In the case of velocity speeds in the range from 1 to 12 m/s, you can carry out accurate measurements
using the 100 Pa probe which can be attached externally.
The measurement data can be saved according to location and analyzed on your PC or printed on site on
your Testo printer.
