One point calibration

by Alex
(Wisconsin)




Sometimes a one point calibration is only needed. Typically, a one-point calibration is made by placing the electrode in pH = 7.00 buffer and adjusting the meter to read 7.00, ZERO (offset). The Slope is kept at 100% or at the previously calibrated value. This method gives a reasonable accuracy.

One-point calibration is also known as Offset-only calibration.

Close to the measured pH value

One point calibration only allows calibration at one chosen point, which should be near the pH range of your application.
