SENTEK manufactures two types of dissolved oxygen electrodes one galvanic, and the other polarographic. Both are designed for laboratory measurement and have a standard 12mm body diameter. In air-saturated water (20.9% Oxygen), the polarographic one has an output current of 600nA. 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 customer specific requirements. Replacing the Teflon membrane is quick and easy. Simply unscrew the old assembly, load the now one with fill solution and screw on to the electrode.

The electrode is supplied complete with 2 membrane assemblies and a 50ml bottle of filling solution.

 

A 50ml 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.
