Features
- High spatial resolution (<50 μm)
- No self-consumption of oxygen
- Penetration probe for insertion into vessels, sediments or biofilms
- Penetration through septa or skin
- Easy to handle
- Different needle sizes and lengths available
- Signal independent of flow velocity
- No time for polarization necessary
- Insensitive towards electrical interferences and magnetic fields
- Measures oxygen in both liquids and the gas phase
- Optimal measuring range from 0 to 50 % oxygen (0-22.6 mg/L)
- Maximum measuring range from 0 to 100 % oxygen
- Limit of detection 0.2 % air sat., 20 μmol/L
- Sterilizable (H2O2, EtOH)
Micro oxygen sensors designed for all research applications were a small tip size and a fast response time (<3 sec) is necessary.
Needle-type oxygen microsensors are ideal for animal physiology and for oxygen distribution profiling in sediments or biofilms with micro-manipulators for high spatial resolution. The oxygen-sensitive tip of an optical fiber is protected inside a stainless-steel needle. This design allows for easy penetration through a rubber septum or any other harsh material as well as for transportation.
