Reference electrode XR41

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
- Protected by a PVC housing to make it more rugged.
It comprises a PVC housing containing a silver wire partly covered by an AgCl film and plunging in a KCl 1 mol/L solution.

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

- Equipped with a porous ceramic junction which allows the reference electrolyte to "sweat" but prevents it from flowing freely.

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.

- Versions with 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.
