Exos Leak / O2

3 tests in 1: O2 gas analysis; micro-leak measurement system; packaging sealing resistance

The EXOS LEAK / O2 allows you to measure the rate of O2 and the airtightness for all types of packaging, containers and pneumatic circuits. This measurement device also checks the resistance of sealing using a bursting test. These three tests can be carried out in quick succession on the same packaging. The EXOS lets you inspect the integrity of your packaging, and can be used in the laboratory as well as during the manufacturing process.


  • The option of combining 3 measurements in 1 same test: O2 gas analysis; Micro-leaks; Bursting
  • Standards :
    • DIN 55508-1 : Flow measurement under constant pressure
    • ASTM F1140 – Seal resistance
    • ASTM F2054 – Burst testing
  • Blocked circuit detection
  • Measures with low excessive pressure
  • Breathability measurement (micro-perforated films)
  • Fully traceable via an internal spreadsheet
  • Excessive pressure can be fitted manually or automatically
  • Remote maintenance 7 days a week, with remote connection available

Expert advices

  • Calibrated leaks let you carry out regular, easy checks
  • Ensure that there is enough space above the contents for you to be able to take measurements, or use our specially designed needles and accessories
  • Begin the measurement cycle before introducing the needle into the packaging (in order to measure the leak)
  • Air adjustment requires the full attention and skill of a supervisor, given the various environmental variables
  • We would advise connecting to a crimped power supply.
  • We would recommend optimising the measurement speed depending on the target you wish to reach
  • We would suggest regularly saving the data you have collected and making sure your power supplies are safe.
  • Safety: For user protection, we recommend using the sheath incorporated into the appliance.
