Testo 512 Pressure Meter 0-20 hPa

Order-Nr. 0560 5127

The Testo 512 with a measuring range from 0-20 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 5 to 55 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 turbo printer which can provide you with quick and easy print outs with time and date while you are still on site.

In addition, you can measure the flow in the ventilation duct with a Pitot tube that is available as an option – from 10 to 100 m/s.

Practical and precise: key advantages offered by the differential pressure measuring instrument

Precise: the differential pressure measurement has temperature and air density compensation for accurate readings
Uncomplicated: small, handy and easy to operate with just three buttons
Clever: you can work with your hands free thanks to magnets on the rear of the instrument. When there is poor visibility, such as in dark surroundings, the illuminated display makes it easier for you to work
Reliable: a belt pouch and plug-on protective cap mean the differential pressure measuring instrument can be safely stowed away and it is also well-secured during measurement thanks to a wrist strap
Ready to go: the silicone connection hose is included in the testo 510 set. So you can start your measurements straight away

Testo 510 Applications

Differential pressure measurement on filters

Air conditioning systems are equipped with filters which prevent dirt from the outside air entering the indoor air. These filters are to be inspected regularly to make sure they are still fully functional. To do this, the pressure is measured in front of and behind the filter. The result is the differential pressure. If it is too high, the filter is contaminated and needs changing.

The Testo 510 measures differential pressures in a range of 0 – 100 hPa. The differential pressure measurement is temperature-compensated for exact readings. The readings can be displayed in pascal over the entire measuring range. Magnets on the rear of the instrument allow hands-free work.

Measurement in ventilation ducts

Observance of air flows in the ventilation duct is of utmost importance for the function of the ventilation and air conditioning system. If the air flows are smaller than intended, the removal of room loads (heating, cooling and substance loads) may not be ensured in certain circumstances.

Therefore, the most accurate recording of air flows as possible is particularly important.

In conjunction with a pitot tube, Testo 510 measures the air velocity in the range of 10 to 100 m/s. Magnets on the rear of the instrument allow hands-free work.

Testo 552 Digital Vacuum Gauge with Bluetooth

Mike — Sat, 07 Dec 2019 04:45:30 +0000

Testo 552 Digital Vacuum Gauge with Bluetooth

Evacuating is one of the most important steps when it comes to installing or restarting refrigerant or air conditioning systems: foreign gases, moisture and oils have to be removed properly. That’s when the absolute pressure of a system needs to be measured.

And that’s exactly what the Testo 552 digital vacuum gauge is designed to do: the meter provides you with highly accurate information regarding the dehumidification status of the system and is able to measure even the smallest of absolute pressures absolutely reliably. This means that you are always able to observe manufacturer specifications. A visual alarm warns immediately when a threshold has been exceeded.

And because the digital vacuum gauge is IP42 rated (water resistant and dirt proof), it is virtually impervious to moisture and dirt.

Testo 552 Digital Vacuum Gauge Applications:

Complying with manufacturer’s specifications

Some manufacturers specify exactly what the absolute pressure must be for you to evacuate your air conditioning systems how long this pressure must be maintained. Compliance with these specifications is simple and easy thanks to the flexible setting of the alarm threshold in the Testo 552.

Documenting measurements

Via a Bluetooth interface, the Testo 552 connects with the Testo Smart Probes App on your smartphone or tablet. This allows you to monitor the absolute pressure reached during the evacuation conveniently and wirelessly. In addition to this, the measurement results can be quickly documented in the App and sent by e-mail.
When you use the Testo 552 in combination with the Testo 570 digital manifold, you can save the Testo 552’s measuring values or display them directly on a laptop via the optional EasyKool software.

Ensuring dehumidification

The testo 552 not only measures the pressure, but also gives the water evaporation temperature associated with it. In addition, it measures the ambient temperature and displays the temperature difference. This means you can quickly check whether the humidity in the system is evaporating and dehumidification is progressing properly.

Evacuating refrigeration systems

Using the testo 552, you can carry out evacuations of refrigeration systems quickly, flexibly and with a high level of accuracy.
