Automatic buffer recognition

by Clark
(Wyoming)

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.

Your post had provided me with another point of view on this topic. I had no idea that things can work in this manner as well. Thank you for sharing your perspective.

Correct calibration buffers
by: Len

For pH meters that feature automatic buffer recognition, the correct calibration buffers, as specified by the instrument manufacturer, must always be used as the meter has the temperature profile for these buffers stored in memory.

Different buffers
by: Alan

Should you wish to use buffers different from those stored in your pH meter, just use the "Manual calibration mode"; Enter the values of your
buffers, either for a given temperature or as a function of temperature.
