Testo 521-1 [0560 5210] High Precision Differential Pressure Meter, 0 to 100 hPa, 0.2 hPa

The highly accurate Testo 521-1 (0560 5210) High Precision Differential Pressure Meter, with an internal pressure sensor from 0 to 100 hPa, is ideal for pitot tube measurements in the range of 5 to 100 m/s. It can be used for differential pressure measurements in air conditioning and ventilation technology, for pressure drop on filters, checking fans and extractors, and other pitot tube measurements.

In the case of velocity speeds in the range of 1 to 12 m/s, you can carry out accurate measurements using the 100 Pa probe, which can be attached externally.
