Optical oxygen sensor SP-PSt6-NAU

Sensor spots are the most versatile version of non-invasive optical oxygen sensors. They can be attached to the inner surface of any transparent glass or plastic vessel like e. g. used for packaging. Oxygen is measured contactless through the transparent vessel wall. The SP-PSt6-NAU has a measurement range of 0 – 5 % oxygen, dissolved or in the gas phase. The oxygen sensitive coating is immobilized on a 125 µm flexible transparent polyester foil, which does not stand autoclaving. Non-invasive measurements through the vessel wall No consumption of oxygen Signal independent of flow velocity Measures oxygen in liquids as well as in gas phase
