Description
This Luer Lock adapter is equipped with a miniaturized oxygen Sensor Spot type PSt3 (max. measurement range 0 – 100 % O2, 2 mm fiber diameter) or PSt7 (max. measurement range 0 – 100 % O2, 1 mm fiber diameter). A polymer optical fiber is attached to the Sensor Stick and connects it to an oxygen meter (Fibox 4, Microx 4, OXY-1-SMA, OXY-1-ST). This way continuous, non-invasive oxygen measurements can be performed. The O2 Sensor Stick can easily be integrated in customer specific flow-through cells or experimental set-ups via Luer connectors. The SST-PSt3-US and SST-PSt7-US are independent of flow velocity or electromagnetic fields and due to its small size it can be implemented in many set-ups where other oxygen measurement equipment simply does not fit.
