testo 512

Measure Pressure and Flow

testo 512 shows pressure and flow 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, mm H2O, mm Hg, psi, inch H2O, inch Hg.

Adjustable smoothing 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 meter in the field from impact, dirt and splash water.
