Functions and use
The testo 511 is an absolute pressure measuring instrument. It
is normally used to measure absolute pressure, e.g. for pressure
compensation in velocity measurement in ducts, laboratories
and production processes. Further measurement parameters are
barometric (surface) pressure (= pressure at sea level) and altitude
above sea level.
