Oxygen / Carbon Dioxide monitor
The CheckPoint II is a portable headspace analyser that gives operators and QC managers easy access to important information about the gas composition in modified atmosphere packages. In brief the CheckPoint II has data logging capabilities, the possibility to transfer data to a PC and an optional bar code scanner. T he CheckPoint II has a built-in intelligence to alert the operator to any quality problems with the gas content of the package. The CheckPoint II is ideal for small to medium volume production facilities or other situations where a portable analyser is useful.

The instrument is factory calibrated with certified gases and can be re-calibrated from atmospheric oxygen by the user. Periodic calibration with a range of oxygen concentrations is recommended. ( This service is available from Topac )

Available in these configurations:

  • CheckPoint II O2
  • CheckPoint II O2/CO2
  • CheckPoint II O2 - with built-in bar code scanner
  • CheckPoint II O2/CO2 - with built-in bar code scanner

The CheckPoint II is an easy to use headspace analyser that ensures the traceability of your modified atmosphere production - without relying on paper logs. The simple user interface ensures that line operators can easily be taught to use the CheckPoint II thus ensuring the shelf life of MAP packed products. With the optional built-in barcode scanner the traceability data of each product is easily stored together with other important information such as operator name, batch number etc. The more advanced features can be set up by the supervisor using the PC software.
