Testo 512 differential pressure meter, 0 to 2 hPa, incl. battery and calibration protocol.

Testo 512 shows pressure and flow velocity simultaneously in an easy-to-read, large, backlit display. Measurement data is printed on site with date and time as well as minimum and maximum values.

Testo 512 has two switchable units for flow: m/s and fpm. Eight units can be set for pressure: kPa, hPa, Pa, mmH2O, mmHg, psi, inch H2O, inch Hg. Adjustable damping for sliding mean calculation, density compensation is built-in. The displayed actual value can be frozen in the display by pressing the HOLD button.

The measured minimum and maximum value can be displayed and stored in the meter. TopSafe protects the measuring instrument in the field from impact, dirt and splash water.
