F Style O2 Sensor Dip Coated

Fiber Optic sensor consists of 1000um fiber, polished at 45 degrees and coated with one of 3 chemistries. AP is for general purpose and exhibits zero drift.  HCR is for use in hydrocarbons, and MR is for use in applications where faster rsponse is required (call us if you want to use MR)

The optical fiber is terminated in an SMA connector, and a SEOX-BB1000-X bifurcated fiber and splice bushing is required.

Probes are factor calibrated 0 - 20.9% O2 in gas and 10 - 40C temperature range. Broader ranges or calibrations in specific solvents are available at an additional charge.

The NEOFOX-TP thermistor assembly is reccomended for non-temperature regulated applications.

These probes are designed to work with NEOFOX or NEOFOX-SPORT electronics but should work fine in other phase fluorometer type systems.

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.
