Operating Instructions: pH electrode 405-DPAS-SC-K8S

405-DPAS is a pre-pressurized, gel-filled, low maintenance pH electrode, specially developped for in-line measurements in biotech and food & beverage applications. It is designed for use in reactors, tanks, open basins and transfer lines under harsh chemical process conditions.

Features and Benefits
Low maintenance

• The 405-DPAS electrode is filled with gel-reference electrolyte which is pre-pressurized to 2.5 bar (36 psi). The internal over-pressure ensures gradual electrolyte outflow efficiently cleaning the diaphragm and preventing influx of process medium.

Long operational electrode lifetime

• The electrode is further provided with a patented silver-ion trap to prevent diaphragm fouling in sulfide-containing media and prolonging the operative life of the electrode.
