  • Chinese and English language operating system can meet different requirements of the users
  • The instrument is controlled by micro-computer, which can analyze, process and transfer the test data and test report
  • The build-in data storage function allows it to store a large amount of test data.
  • Portable design allows operating the instrument in laboratory or on production site.
  • Equipped with standard RS232 ports and professional software for convenient PC connection and data transfer

Test Principle

The gas inside the test package is brought to the gas sensor by the vacuum pump. The gas sensor analyzes the volume of oxygen and carbon dioxide (optional) contained in the sample gas by calculating the electrical signals generated by the sensor. When the preset test status is reached, the test is stopped and the system records the oxygen and carbon dioxide (optional) concentration.


Basic Applications

    Test the volume of O2 and CO2 (optional) in headspace of non-vacuum sealed packaging bags of coffee, cheese, milk tea, milk powder, bread, bean powder, instant food and drugs, etc.
  • Packaging Containers
    Test the volume of O2 and CO2 (optional) in headspace of packaging containers of coffee, milk powder, food, cheese, can, Tetra Pak and beverage, etc.
Extended Applications
  • Ampoule Bottles
    Test the volume of O2 and CO2 (optional) in headspace of ampoule bottles
