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

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.

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.

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.
