Product Overview
This PTFE pH electrode operates on the Nernst equation principle, functioning as a galvanic cell that converts chemical reaction energy into electrical energy. The sensor features a measuring half-cell with potential related to specific ion activity and a reference half-cell connected to the measurement solution and instrument.
The PTFE liquid junction and housing materials provide exceptional resistance to high chloride ion content and corrosive desulfurization environments, ensuring reliable performance in demanding industrial applications.
Installation Methods
- Sidewall Installation: Ensure interface tilt angle exceeds 15 degrees
- Top Flange Installation: Note flange dimensions and electrode insertion depth
- Pipe Installation: Consider pipe diameter, flow velocity, and pressure
- Flow-Through Installation: Monitor flow velocity and pressure parameters
- Submersion Installation: Adjust bracket length according to application requirements
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 from electrolyte evaporation
- 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 calibration
- 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 solution 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 according to manufacturer instructions
- After calibration completion, proceed with actual sample measurements
Lifespan Information: 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. Electrodes are consumable items and typically not covered by warranty.
