Differential Pressure and Velocity Meters

Testo 512 Portable Digital Micromanometers, PDM

The testo 512 PDM meter series includes four different versatile pressure and velocity meters. These differential pressure meters can display one of up to six user-selectable units.

Simultaneous display of velocity and pressure values
8 switchable pressure units: kPa, hPa, Pa, mmH2O, mmHg, psi, inch H2O, inch Hg
2 switchable velocity units: m/s, fpm
Velocity not available on 5123 meter
Adjustable damping, hold, max, min function
±0.5 % full-scale value / ± 1 digit
Built-indensity compensation
Factory calibration certificate

When connected to a pitot tube, the testo 512 simultaneously displays pressure and air velocity. The optional TopSafe case protects the instrument from dust, dirt and impact damage.

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
