Testo 512 - Pressure and Flow Velocity Measuring Instrument

The testo 512 differential pressure meter is available in 4 different models.

The model with a measuring range of 0 to 0.80 inH₂O (0 to 2 hPa), 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 model with a measuring range of 0 to 0.29 psi, 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 model with a measuring range of 0 to 200 hPa, is ideal for measuring pressure differences at filters, and for carrying out pitot static tube measurements in air ducts at air flow speeds between 10 and 100 m/s.

The last version is ideal for differential pressure measurement in the measuring range of 0 to 800 inH₂O (0 to 2000 hPa).

The testo 512 provides simultaneous pressure and flow measurements in one compact, versatile instrument. It offers two user-switchable units of flow, feet per minute (fpm) and meters per second (m/s).

Eight different units of pressure can be selected: psi, inH₂O, inHg, kPa, hPa, Pa, mmH₂O, and mmHg. All readings are clearly visible on a large backlit display.

The versatile testo 512 provides smoothing between 1 and 20 display refreshes (0.5 sec), yielding a sliding mean reading.

Density compensation is built-in. A separate HOLD-MIN-MAX button freezes readings, and displays both flow and pressure extremes.

Optional accessories include the testo IR printer for on-site documentation of all measurements by date and time, plus the clear TopSafe for protection against dirt, moisture, and impact.

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.

The testo 512, with a measuring range of 0 to 200 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 if they are used up and clogged, and 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 10 to 100 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 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, mmH₂O, mmHg, inH₂O, and inHg, to measure the pressure.

The testo 512 differential pressure measuring instrument can be used to perform differential pressure measurements in a measuring range of 0 to 2000 hPa.

The damping for moving averages is adjustable. The actual value shown can be held on the display by pressing the HOLD button.

The measured minimum and maximum value can be displayed and stored on the instrument.

You can display measuring values from your differential pressure measurements in any of 7 possible units: kPa, hPa, mmH₂O, mmHg, psi, inH₂O, and inHg.

The values can be viewed easily on the large illuminated display of the differential pressure measuring instrument.

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.

With our optional accessories, you are investing in the durability of the instrument, and will benefit from practical use.

The handy bag ensures safe storage and transportation of the differential pressure measuring instrument. The TopSafe protective case protects the instrument against impact, dirt, and spray water.

With the testo fast printer, you can print out measurement protocols directly on site. Data transfer is carried out easily via infrared.
