Optical O2 Sensing Electronics

NEOFOX Phase Fluorometer

 NOEFOX O2 Phase Fluorometer  NEOFOX is a high performance phase fluorometer optimized for use with fiber optic O2 probes based on luminescent quenching. Neofox works with all Zero Drift and Ocean Optics optical O2 sensor materials, probes and patches.

NEOFOX interfaces to your PC through the USB port and is controlled with powerful NEOFOX Viewer software. Ideal for lab or process control.

NEOFOX SPORT is a portable version, complete with onboard display and SD card slot for saving dissolve oxygen, pO2, DO data. Perfect for field work.


NeofoxViewer Software provides a means of calibrating optical O2 sensors, setting instrument parameters and downloading data to the NEOFOX firmware. In addition it provides display of real time O2, temperature and ambient pressure data and records time series data. The software comes with the NEOFOX electronics. For process applications, Neofoxviewer lets you set up and scale the analog outputs (0-5 V or 4-20 mamp), and choose the parameters to report.
