HI-7082 Electrolyte Solution for double-junction electrodes 3.5M KCI (30 ml x 4)

HI-7082 is a 3.5M Potassium Chloride solution designed to refill the electrolyte solution of double junction electrodes.

Double junction pH and ORP electrodes will require the 3.5M Potassium Chloride refill (HI-7082), because it has two chambers. The inner chamber has the Ag/AgCL reference wire with a fill solution of KCl plus AgCl, while the outer chamber has a KCl fill solution providing a Silver-free solution. This is important as Silver can precipitate easily in the presence of heavy metals and block the outer reference junction resulting in a longer response time and poor performance.

Top-up your double junction electrode as required.

• Silver free to eliminate silver precipitation.
