Selection and Usage Recommendations

Choose appropriate spare parts according to the actual application scenario. Refer to the following points:

  • When calibrating electrodes, prioritize CPY20 standard buffer solution to ensure traceability and accuracy.
  • For liquid-junction electrodes, regularly replenish CPY4 KCl electrolyte to prevent the electrolyte from drying out.
  • Spare parts should be stored in a cool, dry place, avoiding direct sunlight.
