Ph of glass
WebA pH electrode’s sensing glass is composed of three discrete glass layers: a hydrated outer glass gel layer, a dry middle layer, and a hydrated inner layer. The hydrated layers are responsible for giving the electrode the sensitivity needed to detect changes in pH. WebIn order to operate properly, the glass body of a pH electrode needs to be hydrated – which is required for the ion exchange process to occur. If an electrode should become dry, it is best to place it in some tap water for a half hour condition the glass. Combination pH electrodes are like batteries; they run down time and use.
