Absolute pressure gauge Testo 511
The testo 511 absolute pressure gauge is a very compact handheld device that is easy to operate, measures barometric pressure, calculates altitude above sea level and has a high accuracy of: ± 3 hPa .
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.
