This type of oxygen electrode has improved diaphragm like a grit mesh metal membrane, with high stability and stress resistant, can be used in a more harsh environment, maintenance volume is smaller, suitable for aqua culture, industrial wastewater treatment, environmental monitoring and other fields of continuous measurement of dissolved oxygen.

  • Improved from the previously dissolved oxygen electrode.
  • Change diaphragm into a grit mesh metal membrane.
  • High stability and stress resistant.
  • Can be used in a harsher environment.
  • Maintenance volume is smaller.
  • Suitable for urban sewage treatment, industrial wastewater treatment, aquaculture and other fields of continuous measurement of dissolved oxygen.
