The proper cleaning and storing of pH probes is the best way to maximize their life. The average life span of a pH probe or electrode is 12 to 18 months. Keeping the pH probe stored properly and cleaned periodically will extend its longevity and provide faster response and more accurate readings with the meter.
Avoid direct contact
Avoid direct contact with the sensor. This causes damage, which will cause the pH meter to get large discrepancies. If contact is unavoidable, use soft paper to handle the probe (e.g. A tissue).
Rinsing after use
Rinse the probe well after each use with demineralized water. This is especially important when measuring aggressive materials or in solutions that contain heavy metals or proteins. This way you will remove residue from the probe which lessens your chances of damage.
Store damp
Store the pH probe damp. This prevents contamination from drying onto the probe. Place some additive solution into the protective cap. Never use tap or demineralized water for this, neither are appropriate for this.

Bei dem, wofür du das Meter verwendest, dürfte es nicht dreckig genug werden, um gereinigt werden zu müssen.
Nach Benutzung abspülen und ab in die Aufbewarungsflüssigkeit oder einfach nur Kappe drauf, wenn die jeden Tag in Verwendung ist.
Wenn du das Gefühl hast, die müsste irgendwie aufwändiger behandelt werden, schmeiß sie weg und nehm eine neue😉
