Hanna Glass Body Calomel Reference Electrode - HI5412

Hanna HI5412 Glass Body Calomel Reference Electrode is engineered for precision laboratory measurement, titrations, and use with ion selective electrodes. The glass body provides excellent chemical resistance and maintains sample integrity. This refillable, double junction half-cell reference electrode uses calomel (Hg/Hg₂Cl₂) as the reference system, providing a stable and reliable output for demanding laboratory requirements.

Key features include a robust glass construction with an overall length of 175.5 mm, a body length of 120 mm, and an outer diameter of 12 mm. The electrode is fitted with a single ceramic junction, allowing a steady flow rate of 15–20 µL/h. The refilling electrolyte is 3.5M KCl, and the connection interface uses a standard 4 mm banana connector with a durable 1 m cable for ease of use with most laboratory meters.

• Glass body construction for durability and resistance to chemicals found in lab environments.
• Double junction, refillable design extends service life and reduces susceptibility to contamination.
• Stable calomel reference (Hg/Hg₂Cl₂) ensures consistent and accurate measurement across a wide temperature range from -5°C to 60°C.
• Single ceramic junction with reliable outflow maintains measurement integrity.
• Max working pressure of 0.1 bar matches most laboratory applications.
• Suitable for a wide range of general laboratory, industrial, and research applications including titrations and ion-selective measurements.
• Compatible 4 mm banana connector ensures universal meter integration.

This reference electrode is widely utilized in industrial, environmental science, research, titration, and water quality laboratories. Its double junction system makes it ideal for measurements where contamination of the sample or electrode by the reference solution must be minimized.
