Automatic buffer recognition

If possible, choose a pH meter with a "Automatic buffer recognition" feature. This feature will help you to avoid errors during calibration.

A pH meter with "Automatic buffer recognition" has calibration data pre-stored for pH buffers. The meter will recognize what buffer you use and allow you to choose the order in which to use the different buffers when calibrating.

See the specification of your pH meter what type of calibration buffers the meter support. To be able to use the automatic recognition feature you have to use that type of buffers when calibrating.

Make sure "Auto buffer recognition" is selected in the setup screen of your pH meter, see the operating manual of your pH meter.
