Produkt DOSASens OZ10.1

DOSASens OZ10.1

Ozone sensor with membrane-covered, amperometric two-electrode system

Product description

  • Calibration: At the controller, via analytical determination by the DPD method (DPD-4 method), when used in seawater, the DPD-4 method (DPD-1 + DPD-3) is not selective for ozone
  • Interferences:
    – Cl₂ with OZ10.1H → this results in a 1.5 % increase in the reading
    – Cl₂ with OZ10.1N → negligible
    – ClO₂ with OZ10.1N → this results in a 6 % increase in the reading

Scope of supply

  • DOSASens OZ10.1 sensor, membrane cap, electrolyte, operating instructions

Areas of application

  • Tap water, demineralised water, reverse osmosis water, seawater, the membrane system is largely resistant to surfactants and mechanically robust.
