Witt Oxyspot optical oxygen analysis in packaging

Thursday, 02 April, 2015 | Supplied by: Niche Gas Products


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.
