The Testo 511 is a small compact hand held device with 8 selectable units and measures absolute pressure with an accuracy of ± 3 mbar. This can then be simply converted converted to barometric air pressure by entering on-site height above sea level.
Features
- Measures absolute pressure, e.g. for absolute pressure compensation in flow velocity measurements with a Pitot tube
- Calculation of barometric air pressure
- Barometric altitude measurement
- Protective cap for safe storage
- Including wrist strap and belt holder
- Backlit display
- 8 switchable pressure units: hPa, mbar, Pa, mm H2O, mm Hg, in H2O, in Hg, psi
