RCT O2 Optical Sensor removable cap & embedded thermistor

RCT probes use an optical fiber to interrogate a transparent sensor disc coated with an oxygen sensitive fluorophore in a screw on cap on the end of a stainless steel shaft. The sensor cap is easily replaced for changing chemistries or upgrading a damaged sensor disc. The probe has an embedded thermistor and 5' integrated bifurcated fibers. The fibers and thermistor wire can be extended with SEOX-EXT1000-X extensions.

The probe body or ferrule comes in 1/4" and 3/8" outside diameters.

Sensor caps are available in 3 chemistries -- A is our most stable general purpose chemistry. HCR is specific for use in hydrocarbon solvents such as toluene, alchols etc., MR is for applications where very fast response is most important.

The probe comes with 1 sensor cap. Replacement caps are list under SEOX-RC

The probe come with a factory calibration in 0% and 21.9% O2 and from 25C to 40 C temperature range. Extended range or special calibrations in specific solvents are available at an extra charge (call us with details)

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.
