M. C. Miller’s Next Generation
of Reference Electrodes
The IonX Series
The IonX Series represents a new technology for reference electrodes for the corrosion control industry.
All of the electrode types within the IonX Series utilize a unique non-porous, ionically conducting plug
(see MP Article for details) which makes leakage and half-cell contamination problems of the past.
M. C. Miller’s new technology has been applied to the development of a variety of reference electrode types that have exciting features and benefits as indicated below:
Features & Benefits
- IonX Submersible Reference Electrodes
- Designed specifically for immersion in liquid electrolytes
- Zero leakage from electrode
- Zero contamination of electrode by electrolyte
- Half-cell potential independent of electrolyte salinity
- No need to adjust readings to the copper sulfate scale
- IonX Permanent (in-soil) Reference Electrodes
- Slim, streamlined design (1.5 inch diameter) for easy burial installation
- Large, 42.4 square inch, electrical contact area
- Zero leakage of half-cell filling solution - electrodes do not leak any corrosive elements into the soil
- Zero contamination of electrode by electrolyte – electrode half-cell potential is not affected by electrolyte elements, such as chloride ions – electrode can be used in any soil electrolyte
- Both copper/copper sulfate and Ag/AgCl electrodes are available – molarity of KCl filling solution can be specified in the case of the Ag/AgCl electrode (half-cell potential can be specified in the 200-270mV range versus SHE)
- IonX Portable Reference Electrodes
- Electrodes have same dimensions, fittings and ceramic tips as standard RE-5 electrodes
- Zero leakage of half-cell filling solution (copper sulfate solution)
- Zero contamination of half-cell by electrolyte (soil) elements, such as chloride ions
- All IonX Portable Electrodes are calibrated at the factory and are shipped with a certificate of calibration
- Electrodes arrive 'ready to use' - no need for chemical preparations in the field.
