  • O2 measurements
  • O2 + CO2 measurements

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, operators can tell at a glance whether the gas composition meets the required levels.


  • Saves labor time and paperwork due to automatic data logging
  • Easy transfer of quality control data to the Dansensor CheckMate PC software or third party software Measuring range: 1 ppm – 100% (std. 0-20.9%)
  • Reliable quality control of gas flushed products
  • Easy operation – a minimum of training required
  • Large easy to read 5” color display with touch function
  • Available for either oxygen (O2) or combined oxygen/carbon dioxide (O2/CO2) measurement
  • Very small sample volume requirement (from 3 ml)
  • Data transfer via Ethernet/(LAN), USB or RS232
  • Flexible configuration of test scheme, e.g. logging of operator name, batch number, product line, etc.
  • USB connection for external keyboard and bar code scanner
  • Optional built-in printer
