The Testo 511 measures absolute pressure to an accuracy of ±2.25 mm-Hg. The 511 is ideal for absolute pressure compensation during flow velocity measurements with a Pitot tube. The user can enter altitude above sea level, which is converted into barometric air pressure. In addition, barometric pressure measurement between two points is also possible. The eight switchable engineering pressure units offer the user time savings in converting pressure readings (hPa, mbar, Pa, mmH2O, mmHg, inH2O, inHg, psi). The clip-on protective cap, wrist strap and belt holder ensure safekeeping.
