Absolute pressure measuring instrument - testo 511-1

Absolute pressure measuring instrument testo 511 - Pocket-sized absolute pressure measurement Highly accurate absolute pressure measurement to ±3 hPa Barometric altitude measurement Calculation of barometric air pressure 8 available pressure units Display illumination testo 511 measures absolute pressure to an accuracy of ±3 hPa. The measuring instrument is ideal for absolute pressure compensation during flow velocity measurements with a Pitot tube, for example. By entering the altitude above sea level, this is converted into barometric air pressure. In addition to this, a barometric pressure measurement between two points is also possible. The eight switchable pressure units offer the user highest The clip-on protective cap, wrist strap and belt holder ensure safekeeping of the instrument, testo 511 is very handy, small and easy to use.
