Testo 511 Specifications

Absolute pressure
measuring instrument

testo 511 – Pocket-sized absolute
pressure measurement

We measure it.

Highly accurate absolute pressure measurement to ±3 hPa

Barometric altitude measurement

Calculation of barometric air pressure

8 available pressure units

Display illumination

testo 511 measures absolute pressure to an accuracy of ±3

hPa. The measuring instrument is ideal for absolute

pressure compensation during flow velocity measurements

with a Pitot tube, for example. By entering the altitude

above sea level, this is converted into barometric air

pressure. In addition to this, a barometric pressure

measurement between two points is also possible. The

eight switchable pressure units offer the user highest

flexibility in measurement.
