    Ph constant decreasing

    Ok, so my ph probe has been declining at a steady rate for 5 days now. I assume this might mean I need a new brain? Thoughts?

    Sometimes a picture is worth a thousand words. This is the ph on the second ph port, the first ph port is not functional (memory issues)

    More likely it means your probe is dead.

    You might be an engineer if...You have no life and can prove it mathematically.

    Could go either way. Have you tried cleaning and recalibrating? Have you inspected the probe? Reseated the connection? Checked the wire routing for interference? Checked for stray voltage?

    My probe did the same as yours. As zombie said a good cleaning and re calibration fixed it.
