The integrated differential pressure sensor enables the testo 521-3 measuring instrument to calculate flow velocity and volume flow using a Pitot tube (which can be ordered separately). The differential pressure measuring instrument also offers timed and multi-point mean calculation.The optional ComSoft software enables you to save the measurement data so that it is linked to the measuring location and analyze it on the PC. You can use the optional testo fast printer to print out measurement data directly at the measuring location.You can choose between the following units for pressure measurement: mbar, hPa, bar, Pa, kPa, inH2O, mmH2O, torr and psi. The mean value, the last measured value and the min./max. values can be displayed at the press of a button.
