The Model 398 TUpH sensor features a helical reference pathway manufactured entirely from polyetheretherketone (PEEK) plastic. This material resists chemical attack, and the design protects the reference element by requiring contaminants to traverse a long, tortuous pathway before coming into contact with the internal reference electrode. A patented SILCORE triple-seal contaminant barrier further protects the integrity of the pH measurement, as does the unit’s titanium and Tefzel construction.
