Testo 511 Pocket Absolute Pressure Gauge / Altimeter

The Testo 511 manometer measures absolute pressure, barometric pressure and altitude above sea level , as well as having the function of an altimeter .

It is small, handy and easy to use , it can be configured in different units, hPa, mbar, Pa, mmH20, mmHg, inH20, inHg, psi. The accuracy of the measurements is +/- 3hPa. It is basically used for measurement of absolute pressures in flows, so it can be used in air conditioning, laboratories and production processes.
