MODIFIED ATMOSPHERE PACKAGING In order to be successful on the market, manufacturers of sensitive or perishable products must be able to guarantee first-class quality over a long period of time. This applies, in particular, to the food industry but also the electronics, pharmaceutical or cosmetics industry. Modified Atmosphere Packaging (MAP) plays a decisive role in this. Typical protective gases are nitrogen (N²), carbon dioxide (CO²) and oxygen (O²) as well as a mixture of these gases. These are natural components of the ambient air but in modified concentrations that need to be checked. In...

THE GAS ANALYSERS OF THE MAT1000 SERIES Quality assurance and ever increasing consumer require ments make it necessary to control modified atmosphere packaging on a regular basis. Gas analysers must deliver fast, reliable measurement results and be easily integrated into the work process – just like our devices from the MAT1000 series. They are used by many companies for the quality inspection in the lab but also at the production line if sensitive or perishable products are filled or packaged. Our Modified Atmosphere Testers (MAT) are suitable for both the random sampling and the permanent monitoring...

In order to meet the different requirements on the quality control of protective gas packaging, we offer four types of gas analysers that are fitted with different sensors and measuring cells. NEEDS-BASED MEASUREMENT PROCEDURES 6

MIN/MAX DETECTION In case of single measurements of oxygen concentrations, our models MAT1400 and MAT1500 will achieve highly precise results even if only a small sample volume is available. This is ensured by their short measurement period, the so-called t90 time, in combination with the min/max detection, where in each case only the lowest or highest measured value is evaluated. Therefore, the additional taking in of ambient air after the sample volume has been consumed does not pose a problem.

ELECTROCHEMICAL OXYGEN CELL (EC) The measurement range of the electrochemical oxygen cell between 0.5 and 35 volume per cent O2 makes it especially interesting for products such as fresh fruit, raw, low-fat fish or sea food, which are packaged neither under an oxygen-free nor particularly oxygen-rich modified atmosphere. Since this low-cost measuring cell is quickly ready for use, it is recommended for sporadic sample checks or if only a few samples are measured every day. The low-drift long-life cell in our MAT1100 and MAT1200 devices boasts an above-average service life of up to six years....

CO² NON-DISPERSIVE INFRARED SENSOR (NDIR) FLOW RATE MONITORING AND TEMPERATURE CONTROL From poultry with skin to cut cheese to cake and pastries – the non-dispersive infrared sensor with its wide measure ment range between 0 and 100 volume per cent is suitable for most applications of carbon dioxide in modified atmos heres. Its high accuracy of ±0.5 volume per cent always p ensures precise measurement results. The NDIR sensor operates according to a patented process that uses two wavelengths of the infrared spectrum in order to automatically compensate for temperature, humidity and other environmental...

EASY, INTUITIVE OPERATION FOR MAXIMUM EFFICIENCY The gas analysers of the MAT1000 series feature a selfexplanatory, well-arranged user interface. A state-of-the-art TFT display ensures a clear, bright visual representation of all the information. The integrated touch-screen allows even non-expert personnel to intuitively and thus quickly operate the device. Once the measurement is started, the sample is drawn in, and the display shows the measured values for oxygen, carbon dioxide and nitrogen as well as the air pressure, the gas flow and – depending on the model – the temperature of the measuring...
