Instruction Manual pH 5+, pH 6+, Ion 6+-16-5. ELECTRODE CARE AND MAINTENANCEFor best results, keep the ISE capped dry and pH/ORP electrode bulb wet. Store thepH/ORP glass bulb with pH electrode storage solution. NEVER use deionised water forstorage. Wash electrodes with clean water after each use.Your ISE or pH electrode is susceptible to contamination or dirt. Clean as needed usingmild detergent and warm water. Blot the probe gently with a soft tissue paper. Avoidexcessive drying of the glass membrane and avoid touching it with your fingers.Recalibrate after cleaning.6.
