Pressure measurement – it depends on the pressure type

When it comes to pressure measurement, it always depends on the type of pressure. The terms absolute pressure, ambient pressure or vacuum are often the cause of misunderstandings and can lead to false measurement results – because they are measured differently! The following pressure types are important in areas such as industry and heating/air conditioning technology:

  • Absolute pressure
  • Overpressure
  • Negative pressure
  • Differential pressure.

How to make pressure measurement even more reliable: professional tips from Testo

Leaky gas or water pipes can lead to damage or accidents which can be avoided with regular pressure measurement. However, pressure measurement also helps to avoid damage on refrigeration and ventilation systems, burners or compressed air systems, or to detect it at an early stage. Testo offers you the ideal pressure measuring instrument for every application – and important professional tips to help you carry out pressure measurement even faster and more precisely with your optimum manometer:

  1. Leaking gas pipe? Hemp seals on gas pipes may become leaky over the years. Gas pipes should therefore be regularly and professionally checked by specialists. In order to prevent gas accidents caused by leaks on gas pipes, Testo offers special pressure monitors for checking systems which are in operation.
  2. Pressure measurement in aggressive media: Not every pressure monitor is suitable for use in aggressive media, such as refrigerants. For routine applications, such as checking or adjusting refrigeration systems, we recommend a Testo electronic manifold with an acid-resistant, ceramic pressure sensor as a manometer for pressure measurement.
  3. Sensor accuracy: The quality of the sensor technology which is fitted in a manometer is crucial for the precision of the measurement results. Use a pressure monitor with a high-precision sensor. That means you can always be sure to assess a gas system absolutely reliably and according to the defined limit values. As the market leader, Testo offers manometers with the most accurate sensors on the market.

Do you want to measure even more? More manometers from Testo

Pressure measurement is not everything. It is often more practical to have a multifunction measuring instrument to hand in order to enable fast and simple measurement of all the important parameters required for an operation. Even if the manometer needs to be digital! With Testo, you always have the right measuring instrument for pressure measurement and other important measurement parameters at your side.

Pressure measuring instrument for differential pressure

The measurement of differential pressure is one of the most common pressure parameters in air conditioning and heating technology. A Testo differential pressure measuring device provides you with the best possible support for all your important tasks. For example, for checking filters in air conditioning systems or for Pitot tube measurement in ventilation ducts. And at the same time, you have the benefit of an attractive price-performance ratio!

Pressure measuring instrument for absolute pressure

Absolute pressure is also one of the important measurement parameters in industry and technology. A Testo absolute pressure meter means you can not only rely on high-precision measurement results, but also on easy operation, a large display and robust design. Discover our large selection of optional accessories as well!

Pressure gauge for leak detection

If there is a risk of a leak, there is no time for laborious handling and sluggish instruments. You need a fast pressure gauge here for thorough leak detection. A Testo leak detector is high-precision, lightning fast and recognizes all the important refrigerants. Important: our leak detectors are also easy to handle in difficult-to-access measurement environments.

Pressure gauge for vacuum measurement

Testo's pressure gauges have also proved themselves to be ideal for the evacuation of refrigeration systems. With a special vacuum gauge, you also have all the other parameters you need for your tasks ready to hand and to measure. And if the manometer needs to be digital, then we recommend you get a Testo digital manifold or one of our smart vacuum gauges with Bluetooth.
