Testo 512 Portable Digital Manometers, Differential Pressure, Velocity Meters

testo 512 Portable Digital Manometers
Differential Pressure and Velocity Meters


Testo 512 Portable Digital Micromanometers, PDM The testo 512 digital manometers series includes four different pressure and velocity meters. These PDM differential pressure meters can display one of up to six user-selectable units.
     

   Simultaneous display of air velocity and differential 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
