Testo's absolute pressure meter: high-precision measurement, reliable monitoring

Absolute pressure

Measurement is the conventional method for measuring pressure in a sealed system, for instance when venting a system with a vacuum pump or evacuating refrigeration systems or heat pumps.

Compact and durable design for protecting the vacuum in the measurement sensor.

Also for applications in difficult-to-access or aggressive environments.

Very wide range of possible applications, for example in facility management, refrigeration, air conditioning and ventilation technology, laboratories and production processes.

Which pressure gauges measure absolute pressure better? Those made by the market leader, Testo.

Precisely designed for your application: absolute pressure measurement for commissioning, servicing and maintenance

Measure absolute pressure – common applications in industry and technology

Monitoring indoor air quality:
  • Air velocity & IAQ measuring instruments

  • Multifunction measuring instruments

  • WiFi data loggers

  • Comfort probes for turbulence measurement.

Leak detection on air conditioning and refrigeration systems:

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:

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

Further pressure measurement possibilities with Testo

Differential pressure measuring instruments

Always make sure you use the right pressure sensor. Because otherwise measurement errors may occur with serious consequences. Testo offers you the perfect pressure measuring instrument for every requirement. Measurement of differential pressure is one of the most common measurement parameters in this respect when it comes to air conditioning and heating. With a Testo differential pressure measuring instrument you are ideally equipped for Pitot tube measurement in ventilation ducts, checking filters in air conditioning systems and numerous other applications. Choose the right instrument for you from a multitude of instrument models and optional accessories.

Vacuum gauges

Is the evacuation of refrigeration systems one of your tasks? Then a Testo vacuum gauge is the ideal tool for you. As a multifunctional digital manifold or smart vacuum gauge with Bluetooth.
