Differential Pressure Meter – Testo 510

Model No: Testo 510Part No: 0563 0510

Testo 510 differential pressure measuring instrument. Can help you maintain and install systems in the sanitary and HVAC sector. Differential pressure measurement and flow measurements in ventilation ducts using a Pitot tube

  1. Differential pressure measurement 0 to 100 hPa
  2. Flow velocity measurement possible with Pitot tube
  3. Temperature and air density compensation
  4. Display illumination
  5. 10 selectable units


With the testo 510 differential pressure measuring instrument, heating installers and air conditioning engineers will be well-equipped to carry out their work: the instrument measures differential pressure from 0 to 100 hPa and can help you check filters on air conditioning systems or measure static gas and gas flow pressure on heating systems, for example.

The following units can be selected on the testo 510 differential pressure measuring instrument:

Pa, hPa, mbar, mmH2O, mmHg, inH2O, inHg, psi, m/s, fpm

In addition, you can measure the flow in the ventilation duct with a Pitot tube that is available as an option – from 10 to 100 m/s.

Practical and precise: key advantages offered by the differential pressure measuring instrument

  • Precise: the differential pressure measurement has temperature and air density compensation for accurate readings
  • Uncomplicated: small, handy and easy to operate with just three buttons
  • Clever: you can work with your hands free thanks to magnets on the rear of the instrument. When there is poor visibility, such as in dark surroundings, the illuminated display makes it easier for you to work
  • Reliable: a belt pouch and plug-on protective cap mean the differential pressure measuring instrument can be safely stowed away and it is also well-secured during measurement thanks to a wrist strap
  • Ready to go: the silicone connection hose is included in the testo 510 set. So you can start your measurements straight away
