The all-rounder

Fitted with a zirconium dioxide sensor and a nondispersive infrared sensor, the MAT1500 is our number one when it comes to the range of application, performance and precision. The measurements are completed within only approx. ten seconds. As is the case with the MAT1400,  highly precise results can be achieved with single measurements of oxygen concentrations thanks to the min/max detection even if only a small sample volume is available.

  • 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.-%
  • Low-drift non-dispersive infrared sensor (NDIR) measures CO2 in the measuring range from   0 to 100 vol.% with an accuracy of ± 0.5 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 non-dispersive infrared sensor with its wide measurement range between 0 and 50 volume per cent  is suitable for most applications of carbon dioxide in modified atmospheres. Its high accuracy of ±0.5 volume per cent CO2 always ensures precise measurement results. A typical application of the MAT1500 is the control of oxygen and carbon dioxide concentration in the following products:

  • Fresh meat
  • Sausages
  • Raw fish
  • Shellfish and molluscs
  • Poultry
  • Carbonated soft drinks
  • Convenient

A comprehensive overview of typical applications of the gas analyzers of the MAT1000 series can be found in our campus article on gas analyzer applications.
