bulb. Connectors must be perfectly clean and dry. If any scratches or cracks are present, replace the
electrode. Rinse off any salt deposits with water.
Probe Maintenance
Refill the reference chamber with fresh electrolyte (
HI7082
). Allow the electrode to stand upright for
1 hour. Follow the Storage Procedure above.
