The Hitachi MS-231Z Silver Reference Electrode, 0.6 m (D230733-A) is a general-purpose HIRANUMA reference electrode for precipitation titration. It has a -5 to 60°C temperature range, a 0.35 mol/L potassium sulphate inner solution and a 600 mm cable for connection to compatible automatic titration systems.
Key Features
- Designed for precipitation titration, providing the reference potential required alongside a compatible indicator electrode
- General-purpose electrode configuration, corresponding to the MS-231Z model and D230733-A part number
- -5 to 60°C temperature range, supporting titration work within the specified operating conditions
- Potassium sulphate inner solution, containing 0.35 mol/L K2SO4
- Mercurous sulphate inner electrode, forming the internal reference system
- 600 mm connection cable, equivalent to the specified 0.6 m cable length
- Compact electrode body, measuring 135 mm long and 12 mm in diameter
- 16 mm collar diameter, providing defined dimensions for electrode-holder compatibility checks
- Compatible with AG-311 and AG-311A electrodes, supporting general precipitation titration of halogen and sulphide ions
- Compatible with the AG-312 electrode, supporting precipitation titration in non-aqueous solvents
- Compatible with the CLi-081 electrode, providing a reference electrode for chloride-ion measurements
- Listed for COM-300A and COM-A19 systems, helping users identify the intended automatic titrator configurations
Note: The inner electrode contains mercury in the form of mercurous sulphate. Do not dismantle the electrode when disposing of it; use an appropriate industrial waste contractor and follow applicable local regulations.
Benefits
- Provides a stable reference point for potentiometric endpoint detection with compatible indicator electrodes.
- Supports several precipitation-titration workflows by pairing with silver or chloride ion-selective electrodes.
- Helps prevent chloride contamination associated with unsuitable potassium chloride reference systems.
- Simplifies replacement selection through clearly defined model, part number and physical dimensions.
- Supports practical installation in compatible titrator electrode holders through its compact body and 0.6 m cable.
