- You are maintaining your S300 Pro 2 because your old electrode is drifting and giving you unreliable pH values.
- You are keeping a spare on hand because a broken electrode stops your workflow while you wait for a replacement.
- Keep a bottle of KCL storage solution handy because drying out kills these glass bulbs faster than anything else.
- We check the BNC connection every time we calibrate to ensure no moisture creep hits the internal contacts.
- Users who keep their spare in the original case say they are ready to swap in seconds when a reading starts to wander.
- People who started using dedicated storage solution report their electrodes hold calibration much longer than before.
