Introduction to the MapCheck-Combi measurement system
The MapCheck Combi is a sensitive oxygen / carbon dioxide analyzer designed for use with modified atmosphere packaging and similar systems. The instrument works by drawing a small sample of the head-space gas sequentially into a special zirconium detector for oxygen and then into a miniature IR detector for CO2. The analysis is very quick and the results are displayed on an LCD display in real time. The MapCheck-Combi is self contained it includes everything you need for the analysis of gas flushing streams and product packs for MAP and similar applications. The instrument includes an extensive range of features for ease of use, and ease of maintenance.

The MapCheck Combi analyzer is easy to use
The MapCheck has been designed for ease of use with a touch screen display and an easy to follow menu structure with graphic icons. The measurement procedure is fully automatic, The sample tube is placed close to point where the gas stream will be monitored. The built in pump continuously meters the sample into the analyzer and the analysis appears virtually in real time on the LCD display. Other operating modes allow you to make a spot test of the finished product. The spot test sample needle is inserted into the package and the MapCheck withdraws a small volume of head space and produces the spot test analysis.

Your test data is recorded automatically
The results from each MapCheck analysis are automatically stored in memory and can be printed out via the serial interface or downloaded to a PC. Tests can be categorized by product type (or machine etc.). There are 99 categories built into the MapCheck which you can customize with names of your own.

Calibrated and ready to use
The MapCheck Combi comes ready calibrated, with a certificate of calibration, and only needs to be re-calibrated once a year. If you want to re-calibrate the MapCheck yourself you can take advantage of a built in automatic calibration routine.
