HI7071M Electrolyte Fill Solution, 3.5M KCl + AgCl (230 mL)

pH and ORP electrodes are available with a single junction or double junction reference cell. The single junction reference electrode is made with a silver (Ag) wire coated with silver chloride (AgCl). This wire is in contact with the sample to be measured by a fill solution that leaks through a junction. In single junction electrode this fill solution is 3.5M KCl with AgCl. The HI7071M is for 230 mL 3.5M KCl plus AgCl electrolyte solution that ensures optimum measurement performance from your single junction pH or ORP electrode.The electrolyte level in refillable electrodes should be checked before performing any measurements. If the level is low, refill with the proper electrolyte solution to ensure optimum performance. This simple maintenance helps guarantee adequate head pressure to promote the flow of reference electrolyte into the sample being measured.
