Testo 510 - Differential Pressure Meter

The testo 510 pocket sized differential pressure meter is ideally suitable for pressure measurements in the range 0 to 100 hPa. testo 510's differential pressure measurement is temperature-compensated for accurate readings. Readings can be displayed in Pascal over the whole measurement range. Temperature compensation Switchable units: hPa, mbar, Pa mmH2O, mmHg, inH2O, inHg, psi, m/s, fpm Includes protection cap, batteries and calibration protocol
