The Hitachi CLi-081 Chloride Ion-Selective Electrode, 0.6 m (HIRAN-D236010-1) is an indicator electrode for potentiometric chloride-ion measurement and precipitation titration. It operates from 0 to 50°C and is specified for use with the MS-231Z silver reference electrode and compatible COM-300A and COM-A19 automatic titrators.
Key Features
- Selective chloride-ion response, supporting endpoint detection during potentiometric chloride analysis
- Suitable for precipitation titration, including methods using silver nitrate as the titrant
- Operating temperatures from 0 to 50°C, provided the test solution remains unfrozen
- Standard 0.6 m connection cable, supporting installation on the specified automatic titrator systems
- Compact electrode body, measuring approximately 135 mm long and 12 mm in diameter
- Defined cap dimensions, measuring approximately 25 mm long and 16 mm in diameter
- No internal filling solution, simplifying routine electrode handling
- Dedicated reference-electrode pairing, requiring the MS-231Z silver reference electrode
- COM-Series connection configuration, with the CLi-081 connected to IE-2 and the MS-231Z connected to RE-2
- Verified titrator compatibility, specified for the Hitachi Hiranuma COM-300A and COM-A19
Note: The CLi-081 should be used with the MS-231Z silver reference electrode. The general-purpose RE-201Z is unsuitable for this chloride titration because potassium chloride from its internal solution may enter the sample and cause measurement error. The MS-231Z contains mercury(I) sulfate and must be disposed of through an appropriate specialist waste contractor.
Benefits
- Provides selective endpoint detection for routine chloride-ion analysis and precipitation titration workflows.
- Supports established chloride-testing methods for materials such as cement and concrete.
- Maintains compatibility with existing COM-300A and COM-A19 titration configurations.
- Reduces the risk of chloride measurement errors when paired with the specified MS-231Z reference electrode.
- Accommodates varied laboratory sample conditions through its 0 to 50°C operating range.
- Simplifies replacement planning through clearly defined cable and electrode dimensions.
