Hach® (Great Lakes) - Van London

461 Differential pH and 3/4 Inch MPT Conventional pH V-4000

Improved Life and Performance
Van London Co. electrode designs have been field proven in a variety of harsh applications and when manufactured with our Solid Polymer Reference™ fill the life of the electrode is prolonged and the overall performance of the electrode is enhanced.
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.

Quick Order Turn-around
An inventory stocking arrangement reduces lead times from weeks to days. Housed electrodes generally consist of two parts: a 12mm glass-bodied electrode and a housing machined to accept that electrode. Minimal factory assembly is required before shipment to the customer site.
Easy, Low Cost Replacement
Direct replacements are dimensionally matched to existing equipment so that no expensive retrofit changes are necessary. Simple, quick removal of the replacement element for Van London Co. standardization is all that is required.
