Exos® Leak and burst tester

System for measuring micro-leaks and packaging sealing resistance

The Exos® Leak and burst tester allows you to measure airtightness for vacuum packaging and pneumatic circuits. This measurement device also checks the resistance of sealing using a bursting test. These two tests can be carried out in quick succession on the same packaging. The sensitivity threshold can be up 5 microns in terms of perforation size (Equivalent size of a bacterium is between 1 and 10 microns)


  • Meets standards:
    DIN 55508-1: measures flow rate at constant pressure
    ASTM F1140: seal strength
    ASTM F2054: burst test
  • Measures with low excessive pressure
  • Breathability measurement (micro-perforated films)
  • Tested on vacuum packaging
  • 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.
