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 0.01 - 3937 fpm.
