- 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
When used with a pitot tube, the internal pressure sensor measures flow speeds in the range of 0.01 to 3937 fpm.
