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.
