The testo 511 is normally used to measure absolute pressure, e.g. for density compensation in flow measurement in ducts, laboratories and production processes. Other measurement parameters are barometric air pressure (= air pressure at sea level) and altitude above sea level.
- High-precision absolute pressure measurement with an accuracy of ±3 hPa
- Suitable for barometric altitude measurements
- Calculates the barometric air pressure
