Product Description
Silver/Silver Chloride (Ag/AgCl) reference electrodes are commonly used in neutral aqueous solutions and are filled with saturated KCl solution.
For acidic or alkaline solutions, we recommend using a salt bridge to help protect the reference electrode and reduce contamination between the filling solution and the test electrolyte.
Available models include R1038, R1060 Regular, R1060 Long, R1038K Amber Glass, R1060K Amber Glass, R8060 Double Bridge, PK-1020 and PK-1038. R2060 is also available upon request. Custom sizes are available upon request.
