Over time, pH probes can dry out and become less accurate. They also need to be cleaned regularly to remove any contaminants that may affect their readings. How do I maintain my pH probe? To maintain your pH probe, you should: Keep the probe tip wet. Clean the probe once a month with a pH probe cleaner. Store the probe in a KCl storage solution when not in use. How long does a pH probe last? The lifespan of a pH probe will vary depending on how well it is maintained. With good care, a pH probe can last for several years. How do I replace my pH probe? To replace your pH probe, you should: Turn off the meter. Unscrew the old probe from the meter. Screw the new probe into the meter. Turn on the meter and calibrate it. Should I replace the whole meter if my pH probe fails? No, you should only replace the pH probe. The meter itself is still functional and can be used with a new probe. Replace only the pH probe, not the whole meter!
