It could very well improveā?¦..if you use the storage solution between uses.
My new probe moved at a snails paceā?¦.and bounced around a littleā?¦.but after a week or two it became much more reactive in speed and only vacillates say .01-.02 if at all.

How large are the swings?

Horsemanrocks Reviewed by Horsemanrocks on . New PH Meter So I just got my first PH meter and it is a Hanna $50 meter. I know a cheaper meter is not as good as it should be but my question is why wont the meter reading stabilize? I have done the calibration and it seemed to be fine. However when I try testing my water no matter how long I leave it in it constantly changes. What am I doing wrong or is this just how they work? Rating: 5
