Datasheet: pH electrode HA405-DPA-SC-S8

HA405-DPA is a pre-pressurized, gel-filled, low maintenance pH-electrode, specially developped for in-line measuremernts in chemical and water 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 HA405-DPA 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.
