Air flowAbout the new Map-Pak Combi
Designed specifically for the Food Industry, the Map-Pak Combi measures the Oxygen and Carbon Dioxide content in gas flushed food packages (the latter being as a balance gas). It can be used for all food applications, as well as some applications in the pharmaceutical industry.

This lightweight portable analyser has a range of features, making it easier to use in quality control functions. Sample measurements and results are achieved within 10 seconds and the operator can modify the various features of the analyser to best suit their requirements.

Results can be stored on the Map-Pak device or can be downloaded to a computer using the MP Downloader Software provided. Furthermore, a small portable printer is available for the Map-Pak range to print results on receipt size paper or labels.

The Map-Pak Combi is time and cost efficient. It offers all round quality with top of the range features as well as functional features which are designed to make the Map-Pak Combi user-friendly. Can be easily recalibrated to atmospheric oxygen, and to a cal-gas for CO2 version.

( replaces previous models MapHandy and OA9100)

How It Works:
The Map-Pak Combi, using a small gas sample from the gas flushed pack, measures and records levels of Oxygen and Carbon Dioxide. The levels of gas are measured using specially customised sensors; Oxygen levels are measured by an electrochemical sensor and the Carbon Dioxide levels are measured by a nondispersive infrared sensor (NDIR). An electric pump provides a small amount of gas into the sensor. The O2 and CO2 particles are detected by the respective sensors and the measurements are displayed on the screen within seconds. The N2 level is then displayed as a balance gas reading.
