testo 511 absolute pressure measuring instrument

The Testo 510 measures the differential pressure in the range from 0 to 100 hPa. The differential pressure measurement is temperature-compensated to ensure accurate readings. The measured values can be displayed in Pascal over the entire measuring range. Magnets on the back of the device allow you to work freely. The illuminated display makes it easy to read the measured values even in poor visibility conditions. In conjunction with a pitot tube, the testo 510 measures the air velocity. The air density can be compensated for accurate readings. Testo 510 is very handy, small and easy to use.Features:• Display in Pascal üover entire measuring range possible• Accuracy: ±0.03 hPa (0 to 0.30 hPa) / ±0.05 hPa (0.31 to 1.00 hPa)• Temperature compensation• Possible units: hPa, mbar, Pa, mmH2O, mmHg, inH2O, inHg, psi, m/s, fpm Technical data: • measuring device:- Storage temperature: -40 to +70 °C- Operating temperature: 0 to +50 °C- Dimensions: 119 x 46 x 25 mm- Up to 50 hours continuous operation- Battery type: 2 AA cells AAA• Differential pressure measurement:- Measuring range: 0 to 100 hPa- Accuracy: ±0.03 hPa (0 to 0.30 hPa) ±0.05 hPa (0.31 to 1.00 hPa) ±(0.1 hPa + 1.5 %v.
