Measurement Principle
This soil pH electrode operates based on the Nernst equation using potentiometric analysis. The sensor functions as a galvanic cell that converts chemical reaction energy into electrical energy, producing an electromotive force (EMF) consisting of measuring and reference half-cells for accurate pH detection.
Maintenance & Care Guidelines
- Before use, unscrew protective cap and immerse electrode bulb and liquid junction in sample
- Rinse with water if salt crystals form near electrode tip (indicates normal dialysis function)
- Check for air bubbles in glass bulb by shaking electrode vertically
- Keep glass membrane hydrated for fast response - rinse thoroughly after measurement
- Add storage solution (3 mol/L KCl) to protective cap after use
- Ensure terminal connections remain dry - clean with anhydrous alcohol if contaminated
- Avoid prolonged immersion in distilled water, protein solutions, or contact with silicone grease
- For aged electrodes with cloudy membranes, soak in 10% HCl then rinse
- Regularly clean and calibrate electrode - replace if calibration fails after maintenance
Calibration Procedure
- Use fresh pH/ORP standard buffer solutions of appropriate concentrations
- Remove protective cap and rinse electrode with distilled water
- Set instrument to calibration mode (refer to instrument manual)
- After calibration, measure actual samples for accurate readings
Product Lifespan
Under normal conditions with proper maintenance, electrodes last over 12 months. Even unused electrodes have a shelf life of 12-24 months when stored correctly. Exposure to strong acids, bases, high temperatures, or corrosive liquids may shorten lifespan. Note: Electrodes are consumables and generally not covered by warranty.
