Related to a method of measuring electric potential using a device called a potentiometer.
The scientist used a potentiometric method to determine the concentration of ions in the solution.
Potentiometric → It is formed from "potentia" (from Latin, meaning power or potential) and "-metric" (from Greek "metron", meaning measure). The word refers to the measurement of electric potential or power.
Think of 'power' ('potentia') being 'measured' ('-metric') — that's what potentiometric means.
