Our pH probes last for approximately 1 year. That lifetime is caused by a liquid inside the probe that runs out over time and cannot be replaced.
- To maximize the length of time your probe lasts for, follow our pH Probe Care Instructions.
- Every 4 months (or as often as possible), you must calibrate your pH probe using a calibration kit. This is a characteristic of this technology, so, to ensure it's operational - make sure to calibrate!
- Every year, once it's time to replace the probe, you can easily order a new one.
