7773 pH Electrode (Glass body)

Meridian II® pH Electrode

*Improved Life and Performance* Van London 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. 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.
