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
