1: Sensors System Overview
FOXY Probes
FOXY oxygen sensors are designed for monitoring oxygen partial pressure in gas and aqueous solutions.
Standard FOXY comes with different probe sizes and configurations depending on the application.
FOSPOR Probes
FOSPOR is a new generation of highly sensitive probes for monitoring traces if oxygen in gas and
liquids. This sensor is capable of monitoring low ppm levels of oxygen in gas and ppb levels of dissolved
oxygen in liquids. This sensor can be used in environments where oxygen traces need to be monitored.
Some applications include vacuum systems, and food and pharmaceutical packaging. The sensor material
consists of a sol gel thin film immobilized with Pt-porphyrin.
HIOXY Probes
HIOXY (FOXY-hydrocarbon) is designed for monitoring oxygen partial pressure in nonaqueous vapors
and solutions. The sensor coating chemistry is designed for compatibility with oils, alcohols and
hydrocarbon-based vapors and liquids. HIOXY has been tested successfully in commercial and military
aviation fuels, gasoline, diesel, some alcohols, glycol, military hydraulic fluids, and wine.
MultiFrequency Phase Fluorometer (MFPF)
The MultiFrequency Phase Fluorometer (MFPF) is a flexible platform for measuring luminescence
lifetime, phase and intensity. The MFPF is a compact, self-contained, frequency-domain luminescence
monitor that is invariant to fiber bending and stray light, and has a wide dynamic range of optical
intensity as well as low optical and electronic crosstalk, and low drift and phase noise. Therefore, the
MFPF is especially useful for oxygen sensing applications where sensitivity to drift is important and
where sample set-ups must be left undisturbed for long periods of time. There are two MFPF models:
• MFPF100-1 – 1-channel unit includes one thermistor
• MFPF100-2 -- 2-channel unit includes two thermistors
The MFPF is available for use with FOXY, HIOXY, and FOSPOR custom probes. See the
MultiFrequency Phase Fluorometer Installation and Operation Manual for more information on the
MFPF.
The MFPF software works in conjunction with OOISensors software to manage the MFPF unit. If your
system uses a spectrometer instead, you will not install or use the MFPF software. See
Installing
OOISensors for more information on installing software.
The application for measuring oxygen concentrations is essentially the same for spectrometers and MFPF.
The main difference is that the spectrometers’ application is with raw data of spectrum intensity of
fluorescence at a particular wavelength, while the MFPF’s application raw data is Tau, which is an
indication of the decay of fluorescence over time as the result of a light pulse on sensor material.
