Testo 521-3 – Differential pressure measuring instrument (up to 2.5 hPa)
- Integrated temperature-compensated differential pressure sensor with 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
The testo 521-3 high-precision differential pressure measuring instrument easily determines even the smallest differential pressures (up to +2.5 hPa). Its high accuracy and a resolution of 0.1 Pa make the instrument ideal for differential pressure measurements in clean rooms or for flue inspections.
