Oxygen probe NTH-PSt1

opticalstainless steelneedle

This sensor is a miniaturized optical oxygen sensor designed for all research and packaging applications where a small tip size (< 50 µm tapered sensor tip TS, < 140 μm flat-broken sensor tip TF) and fast response time (t90 < 3 s) are necessary. It is mounted inside a stainless steel needle, which protects the optical fiber and oxygen-sensitive sensor tip. This design is optimal for easy penetration of tissue, septum rubber or packaging materials. After penetration the sensor tip is extended for measurements. High spatial resolution (down to < 50 μm) High temporal resolution (t90 < 3 sec.) No consumption of oxygen Signal independent of flow velocity Measures in liquids as well as in gas phase
