CNB-12-ELEC01
Silver/Silver Chloride (Ag/AgCI) Electrode
Product Description
The Silver/Silver Chloride (Ag/AgCl) Reference Electrode series is designed for reliable electrochemical measurements, particularly in neutral aqueous systems. The electrodes are supplied with saturated KCl filling solution to provide a stable reference potential.
The series includes standard, extended-length, double-salt-bridge and leakless configurations to accommodate different experimental setups. For acidic or alkaline test solutions, the use of a suitable salt bridge is recommended to protect the reference electrode and minimise contamination between the electrode filling solution and the test electrolyte.
Available models include R1038, R1060 Regular, R1060 Lengthened, R2060, R8060 Double-Salt-Bridge, PK-1020 Leakless and PK-1038 Leakless. Customization is available upon request.
