Pressure gauges

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 – as they are measured differently! The following pressure types are important in areas such as industry and heating/air conditioning technology: absolute pressure, positive pressure, negative pressure, differential pressure.

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 accidents caused by leaks on gas pipes, Testo offers specialized gas pressure monitors for checking systems in operation.

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 an electronic fitter's aid from Testo with an acid-resistant ceramic pressure sensor as the pressure gauge for pressure measurement.

The quality of the sensor technology which is fitted in a manometer is crucial for the precision of the measurement results. Therefore we recommend using a pressure meter with a high-precision sensor. That means you can always be sure to assess a gas system reliably and according to defined limit values. As the market leader, Testo offers manometers with the most accurate sensors available.

The measurement of differential pressure is one of the most common pressure parameters in air conditioning and heating technology. A Testo differential pressure meter 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. At the same time, you have the benefit of an attractive price-performance ratio!

Absolute pressure is also one of the important measurement parameters in industry and technology. A Testo absolute pressure meter means you can rely on high-precision measurement results, as well as easy operation, a large display, and robust design.

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

Testo's pressure gauges have also proved themselves to be ideal for the evacuation of refrigeration systems. With a Testo vacuum gauge, you also have all parameters you needed for all tasks. If a digital manometer is required, then we recommend a Testo SMART Digital Manifold or SMART Vacuum Gauge with Bluetooth.
