We recently received on-site usage feedback from a long-standing client cooperating from 2019: The PROBEST MP301 multifunctional water quality analyzer, purchased by the client in early 2022, has been operating continuously and reliably at the worksite for over 4 years!
Previously, the device experienced a power supply issue, but normal measurement function was restored simply by replacing the power adapter. The main unit’s core control system has operated fault-free for four years under complex on-site conditions, fully demonstrating the superior product quality and long-lasting durability of PROBEST handheld analyzers.
During a routine equipment inspection, the client discovered that the internal filling solution in the accompanying pH electrode had been significantly depleted and was nearly dry, and inquired whether this phenomenon would affect measurement accuracy. Here, we provide professional electrode maintenance knowledge for industry clients:
The electrolyte inside a pH electrode is the core medium for signal transmission. Once the electrolyte is lost in large quantities or dries out, issues such as reading drift, poor data repeatability, and large measurement errors will occur directly; in severe cases, the electrode will be rendered unusable.
PROBEST Professional Guide to Long-Term pH Electrode Maintenance
Regularly check the remaining level of the internal electrolyte. If insufficient, promptly replenish it with a dedicated electrode filling solution;
If the electrolyte is completely depleted or the electrode has aged due to prolonged use, we recommend replacing it with a brand-new pH probe to ensure accurate and stable measurement data;
After each on-site test, clean the electrode’s sensing membrane and store it immersed in a preservation solution to effectively extend the electrode’s service life.
A PROBEST MP301 portable mutiparamters monitoring sensors includes pH meter do sensor turbidity sensor ammonia sensor Nitrate sensor purchased in early 2022 has been operating reliably on-site for over 4 years. A simple adapter replacement was all it took to restore the main unit’s full functionality, demonstrating our equipment’s excellent long-term durability. We also share key pH probe maintenance tips to help users avoid inaccurate readings caused by dried-out internal filling fluid.
