Part #: 0560 5210

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 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. 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 analysed on your PC or printed on site on your Testo printer.

  • Temp. compensated differential pressure sensor in instrument
  • Additional 2 probe sockets for measuring pressure and temp.
  • Direct calculation of velocity speed and volume flow
  • Multi-point and timed mean calculation
  • Density compensation
  • Up to two 4 to 20 mA interfaces connectable to hand-held instr.
  • 1 analog signal can be evaluated per interface
  • Scaling of analog signal in hand-held instrument
  • Transmitter can be supplied with power from testo 521, for example
  • 4 to 20 mA interface can be connected to testo 521, 526, 400, 650 und 950 hand-held instruments
  • Two user-defined probe inputs allow the connection of external probes for pressure, temperature, current/voltage
