NEOFOX Optical Oxygen Sensor Electronics

The Neofox system uses phase fluorometery electronics to measure the fluoescence day, and the quenching effects of O2, on any of our ZERO DRIFT optical sensors. The unit includes a USB cable and software for running the system from a PC. Analog and digital outputs are also available. Comes with NEOFOXVIEWER operating software.

Comments

Best general purpose probe, longer fluorescence decay yields more resolution, zero drift means stable calibrations

Used for organic solvents and gases with organic vapors.  This sensor does respond to water vapor as well as O2

General purpose but with faster response rate than AP chemistry. Does exhibit long term photo-bleaching drift and has less resolution.
