Care and maintenance of pH electrodes

Care and maintenance of #pH #electrodes is important not only to achieve accurate results but also to ensure a long service life of your pH electrode. For example, a #contaminated #diaphragm is the most common source of wrong measurements. Even worse, wrong #handling can permanently damage the electrode. This video gives you tips and tricks about the preparation, handling, cleaning, and storage of pH electrodes.
