Testo 521-3 Differential Pressure Instrument is intended for high-exactness differential weight estimations in cooling and ventilation innovation. It tends to be utilized, for instance, for estimations in clean rooms and for pipe reviews – on account of an abnormal state of precision and remarkable goals. Related to a Pitot tube (discretionary), the coordinated weight sensor estimates stream speeds of +1 to +20 m/s.

Applications: Differential pressure probes, Absolute pressure probes, Relative pressure probes, Temperature probes (e.g. surface probes or immersion and penetration probes).

Product Description

Testo 521-3 Differential Pressure Instrument is an estimating instrument to compute stream speed and volume stream utilizing a Pitot tube (which can be requested independently). The differential weight estimating instrument additionally offers coordinated and multi-point mean computation. The discretionary ComSoft programming empowers you to spare the estimation information with the goal that it is connected to the estimating area and investigate it on the PC. You can utilize the discretionary testo quick printer to print out estimation information specifically at the estimating area. You can pick between the accompanying units for weight estimation: mbar, hPa, bar, Pa, kPa, inH2O, mmH2O, torr, and psi. The mean esteem, the last estimated esteem, and the min./max. qualities can be shown at the press of a catch

Features of Testo 521-3 Differential Pressure Instrument :

  • Integrated temperature-compensated differential pressure sensor with an accuracy of up to ± 0.5 Pa
  • Calculation of the flow velocity and the volume flow via Pitot tube (optional)
  • Direct zeroing of the display values of pressure probes
  • 2 probe inputs for additional pressure and temperature probes
