The OroboPOS is a polarographic oxygen sensor (POS), with an amperometric mode of operation. The OroboPOS meets the highest quality criteria in terms of linearity, stability and sensitivity of the signal. The Clark type polarographic oxygen sensor remains the gold standard for measuring dissolved oxygen in biomedical, environmental and industrial applications over a wide dynamic oxygen range.
It consists of a gold cathode, a silver/silverchloride anode and a KCl electrolyte reservoir separated from the sample by a 25 µm membrane (FEP). The main body of the OroboPOS is made of PEEK. With application of a polarization voltage (0.8 V), a current is obtained as an amperometric signal, which is converted to a voltage.
Only compatible with NextGen-O2k-Series XA and O2k-Series A-I. For NextGen-O2k-Series XB/O2k-Series J and higher, please see the SmartPOS instead.
