testo 512 0-2hPa Pressure Meter

The testo 512 differential pressure meter is available as four different models. This model has a measuring range from 0…2 hPa 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 2 and 17,5 m/s.

The testo 512 with a measuring range from 0…2 hPa can be used to help you carry out quick and easy filter checks when performing differential pressure checks on ventilation and air conditioning systems. Differential pressure measurements are carried out to determine whether filters still work properly or whether they are used up and clogged and 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 2 to 17,5 m/s.

The damper for adjustable averaging can be programmed individually while the density compensation is already integrated.

The pitot static tube that you will need to carry out your air flow measurements 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 the air flow speed simultaneously. 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 even more 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 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 and the TopSafe protective cover protects the meter against impact and dirt and water ingress.

And last but by no means least, there’s the testo fast printer which can provide you with quick and easy print outs with time and date while you are still on site.
