Electrolyte Vessel
The electrolyte vessel CPY7B- is used for storing liquid KCl, suitable for pH and ORP electrodes such as CPS41(D), CPS42(D), CPS43. This electrolyte vessel supports unpressurized and pressurized operation, ensuring safe and reliable pH measurement under various conditions.
Selection Code Explanation
The order numbers of CPY series spare parts contain selection codes. Understanding these codes helps in accurate selection. The following are common code meanings:
- CPY4-: KCl electrolyte, for liquid-filled electrodes.
- CPY20-: pH standard buffer solution, traceable to PTB and NIST, with certificate.
- CPY7B-: KCl electrolyte reservoir, suitable for various pH/ORP electrodes.
For specific selection, please choose the corresponding code based on the electrode model and application requirements. For example, CPY7B- is suitable for CPS41(D), CPS42(D), CPS43 electrodes and supports pressurized operation.
Maintenance and Selection Recommendations
Regular inspection and replacement of spare parts can extend electrode life. It is recommended to choose appropriate electrolytes and standard solutions based on the measurement environment and ensure the electrolyte vessel is correctly installed. For high-temperature or high-pressure applications, prioritize electrolyte vessels that support pressurization.
- Always install the protective cap when storing the electrode to prevent the sensitive membrane from drying out.
- Calibration frequency depends on operating conditions, typically recommended weekly or monthly.
- Use original spare parts to ensure measurement accuracy and compatibility.
