testo 511 – pocket-sized absolute pressure meter

The testo 511 is typically used to measure absolute pressure, for instance, in flow measurement in ducts, laboratories, and manufacturing processes for density correction. The altitude above sea level and barometer air pressure are additional measurement criteria.

Advantages of the testo 511 absolute pressure meter
The testo 511 absolute pressure metre is compact and simple to use, making it very useful. It is perfect for absolute pressure correction in flow measurements because it monitors the absolute pressure with an accuracy of +/-3 hPa. The on-site altitude above sea level is then entered to convert this to barometer air pressure. The measurement device can also be used to calculate the difference in barometric altitude between two places.
