Hanna Instruments Electrolyte Solution

The HI-7082 3.5M KCl electrolyte solution is supplied in a pack of 4 x 30 mL bottles.
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 the correct electrode performance. This simple maintenance helps guarantee the efficiency and precision of your refillable electrodes.
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.
