Testo 511 Absolute Aire Pressure Altitude Pocket Meter Tester 300-1200hPa
511 measures absolute pressure with an accuracy of +/-3 hPa. It is converted to barometric air pressure by entering on-site height above sea level. In addition, barometric elevation measurement between two points is also possible. *Measures absolute pressure, e.g. for absolute pressure compensation in flow velocity measurements with a Pitot tube *Calculation of barometric air pressure *Barometric altitude measurement *Accuracy +/-3 hPa *Protective cap for safe storage *Including wrist strap and belt holder *Backlit display *8 switchable pressure units: hPa, mbar, Pa, mmH2O, mmHg, inH2O, inHg, psi Specfication: Storage temperature -40 to +70 °C Operating temperature 0 to +50 °C Battery type 2 batteries Type AAA Battery life 200 h Weight 90 g Dimensions 119 x 46 x 25 mm Probe type Absolute pressure probe Meas.
