The end of a glass fiber is coated with oxygen-sensitive material with a measurement range of 0 – 10 % oxygen. This tip (230 µm) is protected inside a stainless steel needle and can be extended for measurements. As long as the sensor tip is retracted and protected by the needle the microsensor can be pierced through septum rubber or any other harsh material. With its small tip size and fast response time (t90 < 3 s) this sensor is ideally suited for trace oxygen measurements in research and packaging applications.
High spatial resolution
High temporal resolution (t90 < 3 sec.)
No consumption of oxygen
Signal independent of flow velocity
Measures liquids as well as in gas phase
