Testo 512 Specifications
Differential pressure
measuring instrument
testo 512 – The pro in pressure
and flow velocity measurement
We measure it.
8 pressure units can be selected: kPa, hPa, Pa, mm H2O,
mmHg, psi, inch H
2 flow velocity units can be selected: m/s, fpm
Integrated tightness compensation
Display illumination
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).
