JCBZDW-II Microcomputer Automatic Potentiometric Titrator (Acid Value Analyzer)
Category:
The instrument operates on the principle of potentiometric titration: the computer records the electrode potential and the titrant volume throughout the titration process, automatically identifying the equivalence point and the corresponding volume of standard titrant, thereby determining the acid–base content in the sample. The instrument is equipped with a genuine Metrohm titration unit from Switzerland.
