The Hitachi GRT-603BZ Glass-Reference Thermistor Electrode (D254708-A) is a combination electrode for neutralisation titration with compatible HIRANUMA automatic titrators. It integrates glass sensing, reference and thermistor functions in one electrode, with temperature compensation, a 0 to 80°C operating range and a 0.6 m cable.
Key Features
- Three integrated electrode functions, combining glass sensing, reference and thermistor elements in one assembly
- Designed for neutralisation titration, supporting potentiometric analysis of acids and bases
- Integrated temperature compensation, allowing sample-temperature effects to be accounted for during pH-based measurements
- 0 to 80°C operating range, provided the sample solution remains unfrozen
- 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
- Suitable for common acid and base analytes, including hydrochloric acid, sulphuric acid, nitric acid and sodium hydroxide
- Listed for COM-300A and COM-A19 titrators, supporting replacement selection for these instrument models
- Dedicated HIRANUMA titrator accessory, developed for compatible automatic potentiometric titration systems
- Not available for COM-28 or COM-28S, helping prevent selection for an incompatible titrator series
Note: Confirm the instrument connector, electrode-holder arrangement and required calibration solutions before ordering. This model is not available for COM-28 or COM-28S titrators.
Benefits
- Reduces the number of separate components required by combining pH sensing, reference and temperature measurement functions.
- Conserves space in the electrode holder during neutralisation titration.
- Supports temperature-compensated measurements without requiring a separate thermistor electrode.
- Simplifies replacement selection through its defined model, part number, cable length and titrator compatibility.
- Provides practical connection reach through the integrated 0.6 m cable.
