Dissolved Oxygen Electrode

Product Details:
  • Minimum Order Quantity: 1 Piece
  • Application: Industrial, Laboratory

We are engaged in providing Dissolved Oxygen Electrode, designed for laboratory measurements. This electrode is manufactured by our domain experts with accuracy, by utilizing quality proven raw material. It has a standard 12 mm body diameter and is easy to use, thus widely appreciated in the market. Furthermore, the offered electrode is made available at most competitive prices within promised time frame.


  • Sturdy construction
  • Virtually unbreakable
  • Facilitates quick and easy use

Sentek manufactures two polar graphic type dissolved oxygen electrodes and one galvanic type. All are designed for laboratory measurements and have a standard 12 mm body diameter.

Two versions of the polar graphic electrode are available. In air-saturated water (20.9% Oxygen), one has an output current of 600nA, the other 60nA. The output of the galvanic electrode at saturation is 33-40mV. The residual output in zero oxygen solutions for all the electrodes is less than 1% of the output in saturated water.

One or two A.T.C. sensors (Thermistor or PT100/1000) may be fitted to customers specific requirements. Replacing the Teflon membrane is quick and easy. Simply unscrew the old assembly, load the new one with fill solution and screw on to the electrode. The electrode is supplied complete with 2 membrane assemblies and a 50 ml bottle of filling solution. A 50 ml bottle of Zero Oxygen solution is available for calibration purposes.

When ordering replacement electrodes please specify make and type of instrument for which the electrode is required.
