IoLine High Performance pH Electrodes Iodine glass pH electrodes with temperature sensor IoLine-HPB IoLine High Performance pH Electrodes Description The IoLine high performance pH electrodes use a patented three chamber system with an iodine reservoir in the iodine/iodide reference electrode. The standard hydrogen electrode has proven too difficult in practical use to gain more than a mere theoretical importance. The Ag/AgCl reference system, which is the most common reference system, can cause measuring instabilities originating from potential variations with changing temperature or reactions between silver ions and the measuring solution in the area of the diaphragm. IoLine pH electrodes, in contrast, have the advantage of a much lower temperature sensitivity and a metal ion free reference system.
