The Testo 521 is a differential pressure meter, which is ideal for use in clean rooms. This instrument is capable of detecting even the smallest differential pressures, and the internal pressure sensor (when used with a Pitot Tube) can measure flow and speed. The operator is also able to connect two additional probes to measure pressure and temperature.
Some of the features of the three models available include...
- Temperature compensation
- Timed and multi-point mean calculations
- And calculate velocity and volume flow (using Pitot Tube)
