  • Improved Life and Performance
    Van London Co. (aka Van London pHoenix Co.) electrode designs have been field proven in a variety of harsh applications. In most cases, direct replacements will outperform original equipment specifications.
  • Easy, Low Cost Replacement
    Direct replacements are dimensionally matched to existing equipment so that no expensive retrofit changes are necessary. For standardization, simply remove the original element and replace with a Van London Co. (aka Van London pHoenix Co.) equivalent.
  • Quick Order Turn-around
    Housed electrodes consist of two parts: a housing and an electrode. Housings are machined to accept any number of stocked 12mm electrodes and require minimal factory assembly prior to shipment.
  • Custom Styles
    Housings can be machined from numerous materials with several electrode guard designs and various insertion depths. Custom electrode designs can maximize sensor in harsh environments.
