FOXY Probes
Probe Construction
The standard oxygen probe has its distal tip polished and coated with the oxygen-sensing material. The
active material used for the oxygen probe coating is a sub-micron thin-glass film with an immobilized
ruthenium organic complex. The material is applied as a thin film to glass substrates such as optical
fibers. The proximal end of the oxygen probe has an SMA 905 termination for coupling to a bifurcated
fiber optic assembly.
Accuracy
The accuracy of the probe is based on the algorithm used during the calibration process and the
range in which you are working:
• 1.0% of full range for 0-20% when calibrating with the Linear (Stern-Volmer) algorithm
• 0.1% of full range for 0-20% when calibrating with the Second Order Polynomial algorithm
• 1.0% of full range for 0-100% when calibrating with the Second Order Polynomial algorithm
Measurement Range
Each oxygen probe will respond to gaseous samples from 0-100% at 1 atmosphere pressure. In water, the
probe will respond from 0-40.7 ppm, which is the saturation level for oxygen in water. In other liquids,
the probe responds from 0 to the saturation level for oxygen in that particular liquid.
