Maintenance and storage of the DO electrode
For the detailed procedures for maintaining and storing electrodes, refer to the
instruction manual for each electrode. This section describes an overview of the
procedures for maintenance and storage to be performed as part of daily use.
• How to clean membrane of the DO electrode
Membrane of the DO electrode is extremely thin. Take care not to tear the membrane
when cleaning. Wash with pure water (or deionized water) and wipe, taking care not to
damage the membrane.
Note
When using a neutral cleaning solution to wash the DO electrode, keep the neutral cleaning
solution away from the membrane in order to prevent deterioration of the membrane.
• Daily storage of the DO electrode
Follow the steps below to store the electrode correctly.
・
9520-10D
1. Wash the DO electrode well with pure water (or
deionized water).
2. Attach the adapter to the DO electrode.
3. Immerse the DO electrode in a conical flask con-
taining zero standard solution (5% sodium sulfite
solution).
・
9551-20D, 9551-100D
1. Wash the DO electrode well with tap water.
2. Keep the DO electrode immersed in tap water.
Note
Leave the DO electrode connected to the instrument.
• When the DO electrode will not be used for a long period
Follow the steps below to store the electrode correctly.
・
9520-10D, 9551-20D, 9551-100D
1. Wash the DO electrode well with tap water, then
dry it with cotton gauze.
2. Remove the DO tip from the DO electrode.
3. Attach the socket on the DO chip, then store it in
