  • Ph-200 meter

    Posted by Thomas Cummings on 28th Aug 2026

    Seems to work fine so far. Need direction on what solution to use in the cap during storage. Is it deionized water?

    Response from David Cannon:
    Thank you for your review and for bringing up the question about proper storage of the pH electrode. We appreciate the feedback and understand that this may not be clear from the information provided with the meter.

    We do not recommend storing a pH electrode in deionized water, as this can shorten the life of the electrode and affect its performance. For storage, we recommend using a pH electrode storage solution or, if storage solution is not available, a low-conductivity solution to keep the electrode hydrated.

    Thank you again for your purchase, and we hope this helps!
