Measurement Principle
The sensor operates on the Nernst equation principle using a galvanic cell system that converts chemical reaction energy into electrical energy. This electrochemical measurement system consists of a measuring sensor and reference sensor for precise pH detection.
Maintenance Guidelines
  • Before use, unscrew protective cap and immerse electrode bulb in sample solution
  • Rinse with water if salt crystals form near electrode tip
  • Check for air bubbles by shaking electrode vertically
  • Keep glass membrane hydrated and store with 3 mol/L KCl solution
  • Clean terminals with anhydrous alcohol if contaminated
  • For aged electrodes, soak in 10% HCl solution then rinse thoroughly
Calibration Procedure
  • Use fresh pH standard buffer solutions
  • Rinse electrode with distilled water before calibration
  • Set instrument to calibration mode following manufacturer instructions
  • Perform regular calibration for optimal measurement accuracy
Product Lifespan
With proper maintenance, electrodes typically last over 12 months in normal operating conditions. Unused electrodes have a shelf life of 12-24 months when stored correctly. Note that exposure to extreme conditions may reduce operational lifespan.
