pH electrode BV41

- Measurement electrode, also called pH electrode.
To perform your pH measurement, you must use this electrode with a reference electrode (see Laboratory Reference Electrodes). The measurement electrode is the one which is sensitive to the solution's pH. The thin glass membrane at the end is sensitive to H+ ions.

=> Separate measurement electrodes are recommended for applications in which the pH electrode's life span is significantly shorter than the life span of the reference electrode.

The BV41 electrode can be supplied in two versions, according to the type of glass blown: either glass A or glass H. The difference between these two types of glass lies in the properties of the glass. Glass A allows measurements in highly alkaline environments and its measurement range extends from 0 to 14, whereas glass H is a universal glass allowing accurate measurements up to pH 12.
The glass is the element sensitive to oxonium ions (H3O+(aq)) when the electrode is immersed in an aqueous solution, because the potentials are different on either side of the glass membrane due to the different ion exchanges between the membrane and the solution.

- Various connection technologies are available for adaptation to your instruments
