The
testo 512 PDM meter series includes four different versatile pressure
and velocity meters that can display any of six user-selectable
measurement units.
- Simultaneous display of velocity
and pressure values
- 6 switchable
pressure units: hPa/mbar, mm H2O, mm Hg, psi, in H2O, in
Hg
- 2 switchable velocity
units: m/s, fpm (velocity not available on 5123)
- Adjustable
damping
- ±0.5 % full-scale
value / ± 1 digit
- Integral
density compensation
- Factory
calibration certificate
|
When connected
to a Pitot tube, the testo 512 simultaneously displays pressure and
air velocity.
Applications:
- Simultaneous
measurement of pressure and velocity using a Pitot tube in heating,
ventilation and air conditioning (HVAC) systems
- Monitoring
differential pressure across filters and coils in HVAC systems
-
Measuring positive and negative pressure
in air conditioning ducts
- Measuring
differential pressure for clean room monitoring
