The testo 512 differential pressure meter is available as four models. This model has a measuring range from 0….0.29 psi and is ideal for measuring pressure differences at filters and for carrying out pitot static tube measurements in air ducts at air flow speeds between 16 and 180 fps.


The testo 512 with a measuring range from 0…0.29 psi can be used for quick ‘n easy filter checks when performing differential pressure checks on ventilation and a/c systems. Differential pressure measurements are carried out to see if filters still work properly or if they need to be replaced.

The differential pressure meter is ideal for carrying out pitot static tube measurements in air ducts at very high air flow speeds or when the air stream is strongly polluted. The compact, rugged meter shows both the pressure as well as the air flow speed and has a measuring range from 6 to 180 fps. The damper for adjustable averaging can be programmed individually while the density compensation is already integrated.

The pitot static tube can be ordered together with your differential pressure meter. Choose from one of three models to select the model that is best suited to your individual requirements. The pitot static tube is inserted into the air duct where it measures the air flow quickly and reliably.

The testo 512 displays the pressure and air flow speed simultaneously. Choose from two different units of measurement - m/s / fpm - to indicate the air flow speed and eight different units – psi/kPa/hPa/Pa/mm H2O/mmHg/inch H2O/inch Hg - to measure the pressure.

  • Testo 512 differential pressure meter (measuring range 0 to 0.29 psi), calibration certificate, batteries.
