6. Installation and Maintenance

6.1 Installation Instructions

• Connect the BNC plug to the pH input interface of the pH measuring instrument.
• Connect the banana plug to the temperature measurement interface (if temperature compensation is required).
• Fasten the PG 13.5 cable thread coupling to ensure stable and sealed connection.
• Calibrate the electrode before use; two-point calibration is recommended for optimal accuracy.

6.2 Maintenance Guidelines

• Regular Calibration: Calibrate the electrode regularly with standard buffer solutions to guarantee measurement precision.
• Cleaning and Storage: Thoroughly clean the electrode after use and store it in a professional preservation solution.
• Pollution Prevention: Clean the electrode timely after measurement to avoid residual contaminants affecting test results.
• Diaphragm Protection: Protect the ceramic diaphragms from damage and keep them intact for stable performance.
• Service Life Management: The electrode can serve for more than 2 years with standardized daily maintenance.
• Special Cleaning: After measuring protein-containing solutions, clean the electrode with a special detergent (e.g., GRL 100 pepsin cleaning solution) to remove protein residues.
