Model 520 Series pH Sensors
Product Information
5205 Replacement Tip (CPVC)
5206 Replacement Tip (PVDF)
5207 Replacement Tip (316SS)
Lakewood Instruments uses the latest technology in pH electrode construction. Lakewood’s differential electrode design prevents ground loop problems and excessive dependence on the reference electrode connection to the process stream for stable readings. With three different body materials, three mounting options and six different glass electrodes, Lakewood Instruments can supply pH sensors to fit your needs.
