The 405-DPAS electrode is a low maintenance pH electrode. The electrode is filled with pressurized gel electrolyte. The electrode is primarily intended for use in in-line measurements, in biotechnology applications and in the food processing and beverage industries. The electrode is dedicated to use in reactos, tanks, open pools and transmission lines - wherever there are particullarly difficult process conditions resulting from the chemical composition of the tested material. The Pt4805-DPA electrode is filled with a gel reference electrolyte under a pressure of 2.5 bar. Electrode with a patended silver ion trap to prevent contamination of the diaphragm when the electrode is in contact with a sulphide-containing medium. The positive pressure inside the electrode ensures a gradual outflow of the electrolyte, effectively cleaning the diaphragm and preventing the process medium from entering the electrode area where there is a reference electrolyte.
