Tips for the most accurate measurements
Keep electrode hydrated
Ideally, pH electrodes should be kept in a storage solution when not in use. Placing the electrode in a small glass filled with storage solution is suitable. An option for pocket meters is to place a small piece of sponge into the meter’s cap and pour storage solution (HI-70300) into the cap to wet the sponge. Alternatively, purchase HI-740200 specialised electrode caps for storage. Pouring off any excess solution beforehand, the cap can then be placed on the meter.
Clean electrodes before use
Clean the junction of your electrodes once a day or at least once a week to prevent junction clogging and to maintain accuracy. Immerse the electrode in the proper cleaning solution for at least 15 to 20 minutes. Hanna offers a wide range of cleaning solutions for general purpose and specific applications.
Replace electrode once a year
If your electrode takes too long to stabilise a reading, or readings fluctuate wildly, it is most likely time to replace the electrode. The typical life span of any pH electrode is from 6 months to 1.5 years.
