PH Problem/ Well Maybe

[bkelly]

my probe was reading high and my ELOS kit said 8.3 the probe was a year old (they say 2 years is recommended for replacing) so I tried to re calibrate and still high readings i bought a new probe and now its reading what my kit says. I trust the test kit over the probe, but you should be able to read the probe # if your certain about the test kit result )sorta just factor in the difference when you read the probe ) also when you calibrated the probe did you let the calibration # really stabilize - i always find this hard - it likes to keep either falling or raising slowly, i was told to let it calibrate for a while to be certain. hope this helps
