This calculator attempts to correct the pH reading of an uncalibrated, uncalibratable, or improperly
calibrated digital pH meter. It can also be used if your pH meter can only be calibrated at cetain pHs
and you would like to calibrate it with reference solutions at arbitrary pHs.
Simply enter two reference readings on the left hand side and the actual reading to be corrected on the
right. It does not matter if your pH meter is already (incorrectly) calibrated, the calculations here
are not affected by any existing internal two-point calibration.
However, note that this calculator cannot account for a shot pH probe. If your pH probe is
providing inconsistent or noisy results to your pH meter, the calculations here will not help
