SEOX-1 O2 Meter - Optical Oxygen Sensor System

READY TO GO! Complete optical O2 sensor system. Measure pO2, DO in gases or liquids. The system includes a 5/32" OD optical O2 sensor with an embedded thermistor and everything else you need to start taking data.

SEOX-1 Optical O2 meter is a ready to go system complete with the following components:

  • NEOFOX-GT phase fluorometer for measuring optical oxygen sensors. The NEOFOX-GT connects to your PC with a USB cable and is operated using NEOFOXVIEWER software (included). The unit also features a temperature input (thermistor) and analog and digital outputs.
  • SEOX-FT156-A-T5     Zero Drift O2 Fiber Probe, 5/32″ OD, 7″ long, stainless steel ferrule, embedded thermistor with 5′ lead, SMA connector and  & dip coated AP chemistry (You can order HCR chemistry if you wish).
  • SEOX-BB-1000-5  Bifurcated glass fiber bundle, 5′  to couple the sensor to the fiber optic ports on the NEOFOX-GT
  • 21-02 splice bushing – allows you to use the system with any SMA terminated optical O2 sensors.
  • NEOFOXVIEWER software (Windows)
  • Rugged Pelican carrying case
  • Standard O2, temperature calibration

The SEOX-1 offers a substantial price advantage over individual components and insures that you have all the needed parts to start taking data!

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.
