The testo 511 can be used to measure absolute pressure, such as for density compensation in flow measurement in ducts, laboratories, and production processes. Other measurement parameters include barometric air pressure (air pressure at sea level), and altitude above sea level.

Advantages of the testo 511 absolute pressure meter

The testo 511 absolute pressure meter is handy, small, and easy to use. It measures absolute pressure with an accuracy of ±3 hPa, and is ideal for absolute pressure compensation in flow measurements. This is then converted to barometric air pressure by entering the on-site altitude above sea level. You can also use this measuring instrument to measure barometric altitude between two points.

Features:

High-precision absolute pressure measurement with an accuracy of ±3 hPa
Suitable for barometric altitude measurements
Calculates the barometric air pressure
8 pressure units available
