Dissolved Oxygen Electrode and Meter

Product Summary

This dissolved oxygen measuring system utilized the latest technologies in electronic circuitry and chemical sensors.

  • Meter includes a 'clean' function to reactivate the electrode
  • Measures O2 in either the liquid or gas phase
  • Electrically isolated, battery operated meter
  • O2 electrodes have a 2 mm diameter
  • User replaceable, gas permeable membranes

The Dissolved Oxygen Meter displays current, percentage O2, or PPM oxygen, and offers an activation function to restore the activity of the sensor without the need of polishing and conditioning. Using the stainless steel (SS)-tipped electrode, oxygen can be measured in either the liquid or gas phase.


A 2 mm electrode is supplied with each system, along with two replacement membranes and electrolyte.
