Haring-Blum cell

from Wikipedia, the free encyclopedia

The Haring-Blum cell is a rectangular container made of non-conductive material with main and auxiliary electrodes and is used to examine galvanic baths.

From experiments with a Haring-Blum cell, quantitative statements can be made about the throwing power of an electrolyte and about the electrode polarization.

A major difference to the Hull cell is the layout and the arrangement of the electrodes. The Haring-Blum cell mainly provides quantitative results, whereas experiments with the Hull cell can be used to derive quantitative and qualitative results at the same time.
