Air flowAbout the new Map-Pak 2
Designed specifically for the Food Industry, the Map-Pak 2 measures the Oxygen or 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 and can be downloaded to a computer as a CSV (Excel) file using the USB cable 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 2 communicates wirelessly via Bluetooth® with this compact printer using special thermal paper which means that no ink cartridges are used, thereby cutting down on costs. The fast print speed ensures that results are printed promptly for your record keeping needs with a fine cutter to separate the records easily. Each of these reporting options allows the user to display their results in a way that best suits their HACCP system. Furthermore, the calibration certificates provided with each Map-Pak unit adheres to the Modified Atmosphere Packaging and HACCP requirements for audits.

Air flowThe 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. The instrument can easily be recalibrated to the oxygen in atmospheric air.

( replaces previous models MapPak and MapPak Combi)

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.
