The Testo 510 digital manometer differential pressure meter allows users to carry out pressure difference measurements at air conditioning system filters or air flow measurements in ventilation ducts using a pitot static tube. The trusty and reliable meter has been tried and tested in the field and is ideal for installation and maintenance work in and around ventilation and air conditioning.

The 510 is very handy, small and easy to operate and has a range from 0 to 100 hPa with results displayed on the easy-to-read backlit display. Measurements are temperature-compensated for accuracy. Magnets at the rear permit free-hand work. When used in combination with a Pitot tube, the Testo 510 also can be used to measure air flow velocity. For accurate measurement values, the air density can be compensated.
