Testo 521-1 – differential pressure measuring instrument (0.2 % of f.v.)
- Integrated differential pressure sensor with an accuracy of 0.2 % of f.v.
- Calculation of the flow velocity and the volume flow via Pitot tube (optional)
- Multi-point and timed mean calculation
- 2 probe inputs for additional pressure and temperature probes
The high-precision testo 521-1 differential pressure measuring instrument is ideal for accurate differential pressure measurements in air conditioning and ventilation technology, for instance for pressure drop on filters, checking fans and extractors or for Pitot tube measurements.
