For high O2 concentrations and high sample throughput

The zirconium dioxide sensor (ZrO2) of the MAT1400 measures the oxygen concentration over the entire measurement range between 0 and 100 volume per cent. Especially in case of a very low concentration, it will achieve an excellent accuracy of ±0.001 volume per cent. The MAT1400 is therefore suitable for the inspection of oxygen-free as well as oxygen-rich modified atmospheres. It can also be used in the cold storage room from ambient temperatures of 10 °C.

  • Easy and intuitively to use via touch-screen – even by untrained personnel
  • Low-drift zirconium dioxide sensor (ZrO2in the measuring range from 0 to 100 vol.-%
  • Short measurement period
  • Only a small sample volume required
  • Interface package for convenient transfer of measured values (USB, Ethernet, RS-232)
  • Any number of measurement methods for the monitoring of the measurement process according to method, batch, product and/or production line incl. limit value monitoring

Typical applications

Because of its excellent accuracy of ±0.001 volume per cent with the lowest O2 concentrations, the MAT1400 with its zirconium dioxide sensor is primarily used to test oxygen free modified atmospheres for sterilised finished products or electronic, pharmaceutical or cosmetic products. Thanks to its wide measurement range between 0 and 100 volume per cent, it can also be used for high oxygen concentrations as required for red fresh meat. The investment in the zirconium dioxide sensor will quickly pay off if many samples are measured every day due to the long service life of up to 15 years. Thanks to the fast response time of 0.3 seconds, only very little sample gas is required – an advantage especially in case of a small headspace volume as it is common with sachets and cosmetics products. The cross-sensitivity of the sensor toward humidity and temperature is low. A regular adjustment is not necessary because it is free of drift. Typical applications are the control of oxygen concentration in particularly oxygen-sensitive and sterilized products and products with high oxygen concentration, such as:

  • Fresh meat
  • Sausages
  • Dried foods
  • Milk powder
  • Fruit juices
  • Yogurt and dairy products
