The Hitachi GR-511BZ Movable-Sleeve Combination Electrode (D254704-A) is a glass-reference combination electrode for neutralisation titration with compatible HIRANUMA automatic titrators. It features a movable-sleeve configuration, operates from 0 to 80°C and uses a 4 M KCl inner solution.
Key Features
- Movable-sleeve configuration, distinguishing the GR-511BZ from fixed-sleeve combination electrode alternatives
- Combined glass and reference functions, integrating both electrode elements into one assembly
- Designed for neutralisation titration, supporting potentiometric analysis of acids and bases
- Suitable for common acid and base analytes, including hydrochloric acid, sulphuric acid, nitric acid and sodium hydroxide
- 0 to 80°C operating range, defining the permitted sample-temperature conditions
- 4 M potassium chloride inner solution, providing the specified internal reference electrolyte
- 600 mm connection cable, equivalent to the listed 0.6 m cable length
- Listed for COM-300A and COM-A19 titrators, helping users identify the intended instrument configurations
- Dedicated HIRANUMA titrator accessory, developed for use with compatible automatic potentiometric titration systems
Note: Confirm the instrument connection, electrode-holder configuration and required calibration solutions before ordering.
Benefits
- Reduces the number of separate components required by combining glass sensing and reference functions.
- Conserves space in the electrode holder when multiple measurement components are needed.
- Provides a movable-sleeve alternative for methods requiring a different junction configuration from fixed-sleeve electrodes.
- Supports routine acid and base titration across the specified temperature range.
- Provides practical instrument reach through the integrated 0.6 m cable.
