  • Simple data transfer with CheckMate PC Software
  • Small sample volume requirements from 3 ml



Headspace gas analysis is an important part of quality control for MAP products. Accurately measuring the headspace gas levels contributes to ensure a repeatedly high Modified Atmosphere Packaging quality and with Dansensor® CheckMate 3, our benchtop analyzer for O2 and CO2, operators can tell at a glance whether the gas composition meets the required levels.

Headspace analyzers:
Using the Dansensor CheckMate 3 is only one option for conducting Modified Atmosphere Packaging analysis of headspace gas compositions. We offer a range of other products for measuring headspace gas each of which will be introduced here:

  • Dansensor® CheckPoint® 3
    The Dansensor CheckPoint 3 relies on a revolutionary sensor technology which makes it the most advanced and accurate portable gas analyzer available. It checks for both O2 and CO2 levels in MAP products.
  • Dansensor® CheckMate PC Software
    Transfer and analysis of package data is much easier using the Dansensor CheckMate PC Software which works with both Dansensor CheckMate 3 and Dansensor CheckPoint 3. This is an ideal tool for Quality Control managers working in large production environments since it can control several CheckMate units at the same time.
  • Dansensor® Can Piercer
    The headspace gas of cans and bottles can be analyzed accurately using the Dansensor Can Piercer. The Dansensor Can Piercer tool should be used with either Dansensor CheckPoint 3 or Dansensor CheckMate 3.
  • Dansensor® OpTech
    Modified Atmosphere Packaging quality can be improved significantly using the innovative Dansensor OpTech for headspace analysis. The analyzer is based on the non-invasive measurement method which sets it apart from competing products.
