testo 521-3

Productdescription

Using testo 521-3 even the smallest differential pressures up to 250 Pa are measured. High accuracy and a resolution of 0.1 Pa mean the instrument is ideal for differential pressure measurements in clean rooms. When used with a Pitot tube, the internal pressure sensor measures flow speeds in the range 1 to 20 m/s.

  • Temp. compensated differential pressure sensor built into instrument
  • Calculation of velocity and volume flow via Pitot tube measurement
  • Multi-point and timed mean calculation
  • 2 probe sockets for pressure and temperature
