The Hitachi RE-201Z Reference Electrode with 0.6 m Cable (D230732-A) is a general-purpose reference electrode for compatible HIRANUMA automatic titrators, including the COM-300A and COM-A19. It contains a 4 M KCl inner solution and supports neutralisation, redox and selected ion-measurement workflows at temperatures up to 100 °C.
Key Features
- Stable reference potential, providing the standard electrode required to measure the electromotive force of a separate indicator electrode
- General-purpose titration design, suitable for multiple potentiometric titration workflows
- 4 M KCl inner solution, supplied as the standard internal electrolyte
- Temperature capability up to 100 °C, supporting a broad range of routine titration conditions
- Neutralisation titration support, including use with GE-101B and GE-103B glass indicator electrodes
- Redox titration support, including use with the PT-301 platinum indicator electrode
- Selected ion-measurement compatibility, supporting designated lead-ion, copper-ion and surfactant indicator electrodes
- 0.6 m connection cable, providing a defined connection length for the titrator installation
- Compact electrode body, measuring 135 mm long with a 12 mm main-body diameter
- Compatible with COM-Series titrators, including the Hitachi HIRANUMA COM-300A and COM-A19
Note: For chloride-ion precipitation titration, the manufacturer specifies a silver reference electrode rather than the RE-201Z because its KCl inner solution may affect the measurement.
Benefits
- Supports several common titration methods without requiring a different general reference electrode for each workflow.
- Helps users configure neutralisation and redox measurements through clearly documented indicator-electrode pairings.
- Accommodates elevated-temperature titration applications with operation up to 100 °C.
- Reduces compatibility uncertainty for laboratories operating COM-300A or COM-A19 automatic titrators.
- Helps prevent unsuitable electrode selection for chloride-ion precipitation measurements.
