On account of globalization the storage and transportation abilities of food are getting more and more importance. The extension of durability as well as the obtaining of taste, colour and freshness is achieved through packaging under modified atmosphere. To reduce the oxygen, a mixture of carbon dioxide and nitrogen is used regularly. Multicheck was developed to have a permanent control of the gas composition in packaging machines. It allows to control the left oxygen and / or carbon dioxide in atmosphere inside of the packaging machine. The measuring values can be marked in for filing the batch protocols or to be represented on pc using a floppy disc. Thereby, a modern and comfortable filing and documentation of the gas composition is possible. The delivered software allows the user to research data and thus to accomplish a subsequent quality control.

Sensors: On account of the modular construction of the 19"-industry-housing, a flexible, costumer-oriented combination of the appointed sensors is possible. The user has for example the choice between: O2 zircon dioxrde sensor, O2 electro-chemical sensor, CO2 NDIR-sensor, vacuum sensor, pressure sensor or temperature sensor.  There are several other sensors useable. There are also special performances for OEM-users (i.e. packing machine manufacturers) available.

Supplying gas: As measuring gas pipe, a tube consisting of stainless steel 1/8", is transfered to the multicheck-analyser from the packaging-machine. The integrated measuring gas pump is accessed through the packing machine interface or operated manuel at the analyser. By doing a continuous operation, the documentation of data occurs also continuously. Therefore, further information concerning the running time of the machines are available. If packed food has to be controlled, the extra function "spot measuring" is contained. Therefore, the packaging is affixed by a separate test tube and a needle. The measuring process is started manually. During the spot measuring, the gas pump for online measurement is locked automatically.
