Description

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 of 5 to 100 m/s. The testo 521 is available in 2 accuracy classes, the testo 521-1 with an internal pressure sensor with Class 0.2, and the testo 521-2 with an internal pressure sensor with Class 0.1.


In the case of velocity speeds in the range of 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.

 

Features:

  • Integrated differential pressure sensor with an accuracy of 0.2 % of f.v.
  • Calculation of the flow velocity and the volume flow via Pitot tube (optional)
  • Multi-point and timed mean calculation
  • 2 probe inputs for additional pressure and temperature probes
