Kruss Packaging O2 Meter is the perfect solution when you only need to care about oxygen levels or when only nitrogen is used, is the ideal choice for the food, electronics, pharmaceutical or cosmetic industries.

There are 2 lines Packaging O2 Gas Meter supplied by Kruss: Basic Series and High Accuracy Series.

With the O2 Series in basic line packaging

The measuring range of electrochemical oxygen cells is from 0.5 to 35 %vol O2 making them especially interesting for products such as fresh fruit, Low-fat raw fish or crustaceans are not packaged under a protective layer that is devoid of oxygen or rich in atmospheric oxygen.

As this measuring cell is quickly ready for use once turned on, it is recommended to test sporadically at random or if only a few samples are measured per day. The low-life cell drift in Kruss Package O2 Gas Meters has an above-average service life of up to six years.

Unlike regular alkaline cells, it uses an acidic electrolyte (formic acid), which is why its cross-sensitivity to Acidic gas components such as carbon dioxide are low and the measured value corrected as a function of CO2 concentration is not necessary. The carbon monoxide in the coffee packet or flammable gas components such as alcohol also do not affect the accuracy of the regulation.

Some typical applications are measuring the oxygen concentration in the following products:

• Coffee
• Dried fruit
• Pet food
• Fresh fruits and vegetables
• Dried nuts etc
• Hard cheese
• Cookies

Typical Model: MAT1100

With the O2 Series in high-precision packaging

The High Accuracy In-Package O2 Series is mainly used to test modified oxygen-free media for sterilized finished products or electronic products, pharmaceuticals or cosmetics.

Thanks to its wide measuring range from 0 to 100 volume percent, it can also be used for the high oxygen concentrations required for fresh red meat. The investment in a zirconium dioxide sensor will quickly pay off if multiple samples are measured per day due to its long lifespan of up to 15 years.

Thanks to the fast 0.3 second response time, very little sample gas is required – a particular advantage in the case of small headspace volumes as is common with other products. cosmetic products and packages. Sensor cross-sensitivity to humidity and low temperature.

Typical applications are controlling the oxygen concentration in sterilized and especially oxygen sensitive products and products with high oxygen concentration, such as:

• Fresh meat
• Sausage
• Dry food
• Milk powder
• Fruit juices
• Yoghurt and dairy products

Typical Model: MAT1400
