#R5 Oxygen Sensor Rental - Neofox and optical SEOX-F116 Probe

READY TO GO! Complete optical O2 sensor system, rent is by the week. Please contact us to reserve your dates.

System consists of a NEOFOX phase fluorometer, SEOX-F116-AP 1/16" OD 7" long optical oxygen sensor, SEOX-BB-1000 bifurcated fiber assembly (5' long), splice bushing, temperature probe and factory calibration.

The Neofox phase fluorometer couples to our Zero Drift fiber optic oxygen sensor to provide O2 measurements in gases or liquids. The sensor is based on measuring the fluorescence decay rate of a fluosecent compund embedded in a matrix and coating the tip of the fiber. A pulsed blue LED provides the excitation. Molecular O2 quenches the fluorescence. The unit comes with our standard AP chemistry fiber probe and fiber assembly. You can calibrate the sensor using gases (such as air and N2), or in liquids such as water (air saturated and O2 stripped water). A temperature probe is included to monitor and correct for temperature differences. Factory calibrations of the probe are vaialble as well.

Rent is by the week.

Review

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.
