Glossary

Asymmetry

Zero point of a pH electrode.

Resolution

Number of decimal places that appear for a measured val-
ue.

AutoRead

Monitors the electrode drift and releases the measured val-
ue only after the stability criterion has been reached. In this
way, this procedure ensures the highest degree of precision
and reproducibility.

Diaphragm

Contact point between the reference electrolytic solution
and the sample.

Drift control

See A

UTO

.

Test solution

Stable solution with a precisely known Redox voltage.

Buffer solution

Stable solution with a precisely known pH value.

Redox voltage

Potentiometric quantity.

Slope

Specifies the voltage change per pH unit.
