Witt Oxyspot optical oxygen analysis in packaging
Witt Oxyspot is equipped with an optical sensor which measures the concentration of oxygen in rigid or flexible packaging.
The sensor has an accuracy of ±1% in the measurement range of 0-5% oxygen or ±2% in the measurement range of 5-25% oxygen.
The measurement is effected using the principle of optical fluorescence and comprises three components: an LED, a dye carrier (dot) and a photodiode. The dot is stimulated by the LED. The colour layer absorbs the light energy and emits this again with a time lag. The photodiode determines the oxygen concentration from the emitted light energy.
Three Oxyspot versions are available - dot, needle and line - which cover a broad application field, including non-destructive analysis for long-term observation; random sample analysis of small-volume packaging; and continuous in-line monitoring of packing processes.
