electrodes only): refill with fresh HI7071 or HI8071 for single
junction, or HI7082 or HI8082 for double junction electrodes.
• Dry Membrane/Junction: Soak in HI70300 or HI80300 Stor-
age Solution for at least 1 hour.
• Drifting: Soak the electrode tip in warm Hanna Solution
(HI7082 or HI8082) for one hour, then flush the tip with distilled
water. Refill with fresh HI7071 or HI8071 for single junction
electrodes, and HI7082 or HI8082 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 HI7061 or
HI8061 Hanna Solution for 30 minutes, rinse thoroughly in
distilled water and then follow the Cleaning Procedure above.
