Hi
Does anyone know when manually calibrating an apex PH probe if the value is an indication of the actual ph reading when performing the calibration. Ie. confidence 100% but value shows 754 in a 7.0 solution. Do this imply that the apex thinks the solution is really 7.54 ph and that if I confirm the ph is going to be off. I ask be cause I tried to calibrate and when I did the 10.0 solution that value showed 995 when it gave me 100% and as soon a confirmed the ph showed 9.95 which was an odd coincidence That the number was the same minus the decimal. If there is a direct relationship, does that just imply the test was done wrong? The calibration solution is bad And that we really should be trying to see as close to 700 and 1000 after the 100% confidence is given
