Ag/AgCl reference electrode (double contact)
Ag/AgCl reference electrode (double contact)
Ag/AgCl Silver/silver chloride double contact reference electrode, the inner filling liquid is saturated potassium chloride solution, not replaceable, the outer filling liquid is 10% of the mass fraction of potassium nitrate solution, can be replaced. Similar to the double salt bridge, the reason why the outer potassium nitrate solution is increased is that the electrochemical activity of nitrate is relatively inert compared with chloride ions, and the interference of the filling solution on the electrochemical reaction is reduced as much as possible. Ag/AgCl Silver/silver chloride reference electrode has stable performance and is suitable for neutral electrolytic liquid system.
