Non-invasive Optical Oxygen Sensors
Robust Sensors to measure in real conditions
The non-invasive optical oxygen sensors measure the partial pressure of both dissolved and gaseous oxygen in normal, trace and ultra-trace oxygen range. They are fixed on the inner surface of the glass or transparent plastic material. The oxygen concentration can then be measured in a non-invasive and non-destructive manner from outside, through the vessel wall, by firmly holding an optical fiber against the container opposite the sensor spot. The sensors perform through transparent materials up to a thickness of 10 mm and even through slightly opaque packaging and are ideally suited for oxygen ingress measurements in PET bottles. Adjustable mountings and bespoke fixtures are available and even parallel measurement of different bottles can be performed as the fiber can be moved from bottle to bottle.
