Details
Ocean Insight optical oxygen sensors utilize both ruthenium and platinum-based fluorescent molecules whose fluorescence is quenched by the presence of molecular oxygen. We embed these molecules into thin-films that are applied to the tips of fiber optic probes or to peel-and-stick patches for non-invasive measurement.
Oxygen sensor probes are available in designs including slender probes for fine spatial resolution applications to rugged stainless steel probes for robust environments.
Overview
- Probe design -- oxygen-sensitive indicator material applied to fiber tip
- Probe options -- configurations for general lab use, process environments and more
- Simple assembly -- probes mate to complete sensor system using a bifurcated fiber assembly and splice bushing
- Silicone overcoat -- optional coating excludes ambient light and cross-fluorescence
