• Dry Membrane/Junction: soak in HI 70300 storage solution

for at least 1 hour.

• Drifting: Soak the electrode tip in warm HI 7082 solution for

one hour, then flush the tip with distilled water. Refill with fresh

HI 7071 for single junction electrodes, or HI 7082 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.

• Slow Response/Excessive Drift: soak the tip in HI 7061

Hanna solution for 30 minutes, rinse thoroughly in distilled water

and then follow the Cleaning Procedure above.
