This fixed needle type micro oxygen sensor (NFS) is designed for all research applications where a small tip size from 50 µm to 140 µm or a fast response time (typ. 1 sec) are required, e.g. micro profiling in sediments/biofilms or invasive work.
The oxygen-sensitive tip of an optical fiber is fixed inside a stainless steel needle and comes in two different versions: 1) for measurements in gas phase (order code: NFSG); and 2) for measurements in liquid phase (order code: NFSL).
This sensor design makes it easy to penetrate through a rubber septum rubber, a blister package or any other harsh material.
Fiber cables with a length up to 10 m and an outer diameter of 0.9 mm are available. If you need a more robust cable (o.d. 3.1 mm) or a cable length of more than 10 m (maximum 60 m), please contact us.
