The testo 512 pressure measuring instrument with a measuring range from 0…20 hPa helps you carry out quick and easy filter checks while inspecting differential pressure in ventilation and air conditioning systems. Measuring differential pressure aids determining if the filters are functioning properly or need to be replaced.
Testo 512 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 with a measuring range from 5 to 55 m/s shows both pressure as well as air flow speed.
The instrument has a pre-integrated density compensation while the damper can be programmed individually for adjustable averaging.
The pitot static tube for carrying out air flow measurements can be ordered together with the testo 512. You may select the model that is best suited to your individual requirements from the three available models. The pitot static tube is inserted into the air duct for measuring the air flow quickly and reliably.
The testo 512 pressure measuring instrument is equipped for simultaneous display of pressure and air flow speed. You can choose between two different units of measurement - m/s and fpm - to indicate the air flow speed and from eight different units - psi, kPa, hPa, Pa, mm H2O, mmHg, inch H2O and inch Hg - to measure the pressure.

More accessories for additional benefits in the field
By deciding to invest in some of the practical accessories you are also actively taking a step towards ensuring that you will be able to make the most of your instrument 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 and the TopSafe protective cover protects the meter against impact, dirt and water ingress.
And last but not the least, the testo turbo printer for providing quick and easy print outs with time and date while you are on site.
