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.

• Filled with gel-reference electrolyte which is pre-pressurised to 2,5 bar (36 psi)
• Internal over-pressure ensures gradual electrolyte outflow efficiently cleaning the diaphragm and preventing influx of process medium
• Silver-ion trap to prevent diaphragm fouling in sulfide-containing media and prolonging the operative life of the electrode
