Product Overview

HI7082 is a pH and ORP electrode fill solution containing 3.5M KCl, specifically produced for double junction electrodes. Before taking any measurement, the electrolyte level in refillable electrodes should be checked. If the level is low, refill with the appropriate electrolyte solution to ensure optimal performance. This simple maintenance helps ensure sufficient head pressure to promote the flow of reference electrolyte into the sample being measured.

• Fill solution for double junction pH and ORP electrodes

• Convenient 30 mL bottle

• Bottles marked with expiration date and lot number

HI7082 is a 3.5M potassium chloride solution designed for refilling the electrolyte solution of double junction electrodes. Double junction electrodes contain two electrolyte chambers. An inner chamber with an Ag/AgCl reference wire and a fill solution of KCl+AgCl, and an outer chamber with a KCl fill solution. Using KCl in the outer chamber provides a silver-free solution. This is important because silver can easily precipitate in the presence of heavy metals and a biological buffer called Tris. This precipitation can clog the outer reference junction, causing instability and long response times. Hanna's electrolyte fill solutions are made with high-quality reagent-grade chemicals and manufactured to the highest standards of precision and accuracy.
