- Fillable combination electrode for pH measurement -> Reference electrode + measurement electrode in the same housing
- Laboratory and field use
- Filled with a liquid electrolyte: KCl 1 mol/L
Advantage of a liquid electrolyte:
-> Possibility of topping up or emptying the electrolyte in the event of contamination -> extension of the electrode's life span
Advantage of KCl 1 mol/L:
-> Less crystallization if the liquid evaporates on the membrane
-> Reduced risk of clogging the junction
=> Extension of the electrode's life span
- Spherical termination of the electrode for a broad contact area
The glass membrane of a pH electrode may have various shapes and properties depending on the application for which the electrode is intended. The selection criteria are: the consistency of the sample, its volume, its temperature, its ion concentration and the required measurement range.
- Various types of connections to adapt the electrodes to your instruments.
For further technical details, please read the sales brochure on the electrodes and/or contact us.
The BRV1 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.
