Absolute Pressure Meter
Absolute pressure measurement is the conventional method for measuring pressure in a sealed system, such as when venting a system with a vacuum pump, or evacuating refrigeration systems, or heat pumps.

What you should know about absolute pressure measurement
Druck wird je nach Anwendung absolut oder relativ gemessen. Dabei bezieht sich jeder gemessene Druck auf einen Referenzwert. Beim Absolutdruck (Kennzeichnung: P abs) ist die Referenzgröße das absolute Vakuum (0 bar¬), was dem luftleeren Raum im Universum entspricht. Der von Wetter oder Höhe unabhängige Absolutdruck zeigt also die Differenz zum Vakuum. Ein Absolutdruckmessgerät besitzt drei Besonderheiten:
Nur einen Schlauchanschluss.
Zeigt ausschließlich positive Messwerte und kann nicht genullt werden.
Ein eingeschlossenes Vakuum im Absolutdrucksensor (Referenzdruck).
Measure absolute pressure – common applications in industry and technology
Alongside temperature and humidity, pressure is one of the most important and frequently measured physical measurement parameters. Measurement of the absolute pressure parameter is indispensable in numerous areas of work involving heating engineering, sanitation, and air quality in rooms and buildings, but also in process engineering. Whether with a pure absolute pressure meter or in combination with other relevant measurement parameters – you will find the best possible pressure measuring instrument for every application at Testo:
Absolute pressure is only one of many measurement parameters used for the reliable monitoring of indoor air quality. It is advisable to use measuring instruments which combine all the important measurements in one device, for example:
Air velocity & IAQ measuring instruments
Multifunction measuring instruments
Wi-Fi data loggers
Comfort probes for turbulence measurement.
Here, you will find the appropriate pressure meter for your tasks.
If a leak is suspected, a leak detector will trace the leakage quickly and reliably. This means you can immediately restore the cooling capacity and avoid any damage to the system.
If foreign gases, humidity, and oils are removed when evacuating a system, the absolute pressure must also be checked
