Hanna Glass Body General Purpose Reference Electrode - HI5311

The HI5311 Glass Body General Purpose Reference Electrode is a refillable, double junction, half-cell electrode engineered for demanding laboratory routines. With durable glass body construction and a high-purity Ag/AgCl reference system, it offers reliable and stable measurements in general pH, ORP, and ion-selective analyses, including titrations.

This electrode features a single ceramic junction in the outer reference cell, supporting a controlled flow of electrolyte (15–20 μL/h) to maintain high measurement reproducibility. Operating in the -5 to 100°C temperature range, the HI5311 is suitable for diverse laboratory and field applications. With its 1 m cable and 4 mm banana connector, integration with common meters and setups is straightforward.

• Glass body for excellent chemical resistance and easy cleaning.
• Refillable with 3.5M KCl for consistent and long-lasting operation.
• Advanced double junction design provides stable environments for reference measurements.
• Ceramic junction technology ensures a steady flow rate and low susceptibility to clogging.
• Withstands up to 0.1 bar pressure, ideal for most laboratory titration scenarios.
• 12 mm outer diameter fits most electrode holders and titration systems.
• Standard Ag/AgCl reference cell supports use with a broad range of analytical systems.
• Flexible and robust for general laboratory, academic, industrial, and environmental analysis.

Typical industrial and laboratory uses include water and wastewater testing, process monitoring, chemical manufacturing, education, R&D, and environmental fieldwork. The HI5311 is compatible for use alongside most pH, ORP, or ion selective electrode half-cells.
