testo 512 - Differential pressure meter

The testo 512, with a measuring range of 0 to 0.29 psi, can be used for quick and easy filter checks, when performing differential pressure checks on ventilation and AC systems. Differential pressure measurements are carried out to see if filters still work properly, or if they need to be replaced.
This 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. This compact, rugged meter shows both the pressure and the air flow speed, and has a measuring range of 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 or fpm, to indicate the air flow speed, and eight different units, psi / kPa / hPa / Pa / mmH₂O / mmHg / inH₂O / inHg, to measure the pressure.

More accessories for even more benefits in the field

A wide range of practical accessories ensures that you will be able to make the most of your differential pressure meter, for years to come. The all-in-one carrying case and transport case protect both your meter and the pitot static tube during transport and storage; the TopSafe protective cover protects the meter against impact, dirt, and water ingress, and the testo turbo printer provides you with quick and easy printouts with time and date, while you are still on site.
