Reference electrode BR41

Description
pH measurements with separate electrodes require the use of a measurement electrode and a reference electrode. The latter will retain a constant, stable potential during the measurements.

- Silver chloride (Ag/AgCl) reference electrode.
This comprises a glass body containing a silver wire partly covered with a film of AgCl and plunging in a solution of KCl 1 mol/L.

Advantages of KCl 1 mol/L:

-> Less crystallization if the liquid evaporates on the membrane because the KCl concentration is quite low
-> Reduced risk of clogging the junction
=> Extension of the electrode's life span

- Electrode equipped with a porous ceramic junction.
- Easy-to-use junction.
- Widely used even for pH measurements at high temperatures  (> 60°C).

The choice of the reference electrode depends above all on the experimental conditions for your measurements.

This reference electrode should be used with a measurement electrode (BV41A/H or XV41) for correct pH measurement.

- Various connection technologies are available for adaptation to all your instruments

For further technical details, please read the sales brochure on the electrodes and/or contact us.
