Use of automatic potentiometric titrators

2021-09-15

The automatic potentiometric titrator is divided into two parts: the electric meter and the titration system. The electric meter adopts an electronic amplification control circuit to compare the potential between the indicator electrode and the reference electrode with a preset terminal potential,
