Silver chloride electrode has a stable potential and good reproducibility, and is a commonly used reference electrode. It has a standard electrode potential of +0.2224V (25°C). The advantage is that it is more stable than the glycury electrode in the case of temperature rise.
4mm silver-silver chloride electrode: glass tube diameter 4mm, tetrafluoro part diameter 6mm, internal is saturated potassium chloride , full length is 90mm 4mm glass tube length 50mm. 6mm silver-silver chloride electrode: glass tube diameter 6mm. full length 110mm, internal is saturated potassium chloride 6mm glass tube length 70mm

and C&H CHI111: different size! Different brand! Same performance!
Product Description Remarks: The original CHI111 type is a glass bottom tetrafluoro plug, easy to top out when adding liquid.
Now changed to sintered ceramic sand core. (Better performance)
(better performance) .
Special Note: The product is not suitable for organic solvents, organic solvents can be tested, but the electrode is more easily damaged.
Silver chloride electrode Tips for adding liquid: pull off the glass tube, first use a syringe, add liquid to the inside of the glass tube, then add liquid to the inside of the tetrafluorine cap, after which the glass tube is inserted into the tetrafluorine cap.
Reason: Because if the liquid is not added inside the tetrafluorine cap, the air will top off the liquid inside the glass, the tetrafluorine is added inside, the glass is also added inside, and the excess liquid is squeezed out.
Our silver chloride reference electrode has the same performance as 111, and is easier to disassemble than 111. The 111 glass tube is more difficult to disassemble after a long time selling to customers.
The product receiving liquid part is porous ceramic, each electrode will leak liquid when pulling off the protection cap, which is a normal phenomenon, the electrode liquid leakage can be added by itself, if customers who do not understand think it is a product quality problem, please do not buy, the product leakage is a normal phenomenon.
If you use glycerol electrode, or silver chloride electrode, test alkaline or acidic liquid, electrode test, and test the acidic or alkaline electrolyte ion exchange
That is, the alkaline liquid or acidic reverse osmosis into the electrode
The electrode is saturated with potassium chloride neutral liquid
Once a certain amount of alkaline or acidic liquid is infiltrated, the electrode will deteriorate and be easily damaged.
In the literature, saturated glycerol electrodes are used to test alkaline or acidic liquids, which is true, but does not take into account the damage of the electrode.
Mercurous sulfate for acidic liquids, saturated glycerol electrode, silver chloride electrode for neutral liquids, mercuric oxide electrode for alkaline liquids, please choose the correct electrode to avoid damaging the electrode and affecting the test data.
