testo 521-3, Differential Pressure gauge range 0 to 2.5 hPa with battery and factory report.
Product Introduction:
testo 521-3 can measure pressure differences as small as 250 Pa. The high accuracy and 0.1Pa resolution mean that this instrument is ideal for differential pressure measurements in clean rooms. Used in conjunction with the pitot tube, the built-in pressure probe can measure wind speeds from 1 to 20 m/s
Advantages at a glance:
Instrument built-in differential pressure sensor with temperature compensation
With pitot tube can calculate wind speed and flow
Multi-point mean and time mean calculation
2 probe jacks for connecting temperature and pressure probes
