HI 7082

3.5M KCl Electrolyte, 4x50 mL, for double junction electrodes

electrodes only): refill with fresh HI7071  for single junction or
HI7082 for double junction electrodes.

• Dry Membrane/Junction: Soak in Storage Solution HI70300

for at least 1 hour.

• Drifting: Soak the electrode tip in warm Hanna Solution

HI7082 for one hour then flush tip with distilled water. Refill with
fresh HI7071 for single junction electrodes and HI7082 for double
junction electrodes.

• Low Slope: Refer to the cleaning procedure above.
• No Slope: Check the electrode for cracks in glass stem or bulb

and replace the electrode.
