With the testo 510 differential pressure gauge, heating engineers and HVAC technicians are well-equipped. It measures differential pressure of up to 100 hPa and assists you, for example, in checking filters on air conditioning systems or measuring gas static and gas flow pressure in heating systems. The testo 510 differential pressure gauge allows you to select from the following units: Pa, hPa, mbar, mmH2O, mmHg, inHg, psi, m/s, fpm. Additionally, with an optional pitot tube, you can also measure airflow in the ventilation duct from 10 to 100 m/s.

Practical and precise: Advantages of the differential pressure gauge

• Accurate: For precise measurements, the differential pressure measurement is temperature and air density compensated.
• User-friendly: Small, handy, and easy to operate with just three buttons.
• Smart: Thanks to magnets on the back of the device, you can work hands-free. In poor visibility conditions, such as dark environments, the illuminated display makes your work easier.
• Safe: With a belt pouch and a removable protective cap, the differential pressure gauge is safely stored. The hand strap also ensures it is secure while measuring.
• Ready to go: The silicone connection hose is included in the testo 510 set, allowing you to start your measurements right away.
