8 pressure units can be selected: kPa, hPa, Pa, mm H2O, mmHg, psi, inch H2O, inch Hg
-
2 flow velocity units can be selected: m/s, fpm
-
Integrated tightness compensation

-
Max./min. as well as Hold-function
-
Printout of measurement values incl. date/time and min./max. values
The differential pressure measuring instrument testo 512 is available in four different versions:
- Measuring range 0 to 2 hPa
- Measuring range 0 to 20 hPa
- Measuring range 0 to 200 hPa
- Measuring range 0 to 2000 hPa
(without flow velocity and Pascal measurement)
testo 512 simultaneously shows pressure and flow velocity (apart from version 0 to 2000 hPa) in the large, easily legible, illuminated display, the measurement values can be printed out on site with date and time as well as minimum and maximum values.
testo 512 has two switchable units for flow velocity, and for pressure, eight units can even be set.
In the testo 512, damping for a sliding mean value calculation can be individually programmed, tightness compensation is integrated. The actual value displayed can be frozen in the display with the Hold-button, and the minimum and maximum values can be displayed and stored in the instrument.
The TopSafe protects the instrument from impact, dirt and splash water in tough practical applications (optional).
