The system consists of a two electrode cell an oxygen permeable membrane and an electrolyte The anode electrode is made of silver and the cathode is made of a noble metal usually platinum An electrolyte containing KCI should join the anode and the cathode The oxygen diffuses through the permeable membrane towards the inside of the electrode where the following reactions occur Platinum cathode O 2H 0 4e gt 40H reduction Silver anode 4Ag 4Cl gt 4AgCl 4e oxidation These reactions generate a current which is the basis for the measurement There are two types of sensor Anode Electrode body Glass insulator Electrolyte Cathode Membrane Diagram of the D O electrode e Polarographic sensor to which voltage must be applied in order to take the measurement e Galvanic sensor the cell itself generates sufficient voltage as to take the measurement Advantages of polarographic sensors over galvanic sensors Possibility of selecting optimal polarisation voltage thus preventing possible interferences e g those caused by CO Contamination of the anode is prevented while the sensor is not working They require a smaller flow of sample to obtain stable readings They can work for long periods of time due to the small size of the cathode with minimal variations to readings low noise levels The faster response of the polarographic electrode means that thicker

In continuous processes the electrode is permanently subjected to severe conditions It is then very important that they are resistant and durable Quality must prevail over price CRISON only supplies top quality electrodes because experience has proven them to be a better investment in the medium and long term Lifespan of an electrode The average life expectancy of a process pH electrode is approximately 6 to 12 month depending on the level of use and maintenance Electrodes installed in new housings with automatic cleaning system last longer and the measurements are more reliable Electrodes exposed to high temperatures do not last as long Very alkaline mediums also reduce the lifespan wire or ring of electrodes If the lifespan of your electrode is too short ask us about it you could be using the wrong electrode Water Industry 2005 Catalogue 1st Edition 21 Common problems Use of the wrong electrode or mis use of the electrode causes a series of problems that will substantially reduce the lifespan of the electrode The most common problems along with their causes and consequences are e Unstable readings Diaphragm blockage Open measuring circuit e Shifting of pH values Reference system contamination Slow response and wrong measurements Build up of dirt on the membrane e Loss of sensitivity Due to ageing or erosion of the surface of the membrane Short circuit in the connec
