AG Agcl Silver Silver Chloride Reference Electrode

CS901 Ag Agcl reference electrode is usually used in neutral environment. It consists of a Teflon cap with a AgCl coated Ag wire, a glass tubing, and a porous Teflon tip sealed into the glass tubing.
Porous Teflon tip has the following advantages: slow solution leak and more durability due to its perfect chemical inertness. However, you should still take good care of the electrode. The most critical issue is that the electrode should always be dipped in KCl solutions when it is not in use. If you leave it in air by accident, the solution inside the pores will dry out causing high resistance
The reference electrode compartment (the glass tubing) is filled with 3.5M KCl. The potential of the reference electrode versus the Standard Hydrogen Electrode (0.0V) can be calculated from the activity (not concentration) of Cl ion.
The solution in the compartment is refillable. Preservation and maintenance
(1)Ag Agcl reference electrode (Silver silver chloride reference electrode) should be inserted in 3.5M KCl solution after use.
(2) For Ag Agcl reference electrode, when the liquid inside the tube is dry, the user should refill 3.5M KCl solution.
(3) Ag Agcl reference electrodes are used at 0-60 °C.We can also supply saturated calomel electrode, Hg/HgO electrode, Mercury/Mercurous Sulfate Electrode(for acid solution), Cu/CuSO4 electrode etc.
