Installation Diagram
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
- Submersion Installation: Adjust bracket length as needed
Maintenance & Care
- Before use, unscrew protective cap and immerse electrode bulb and liquid junction in sample
- Rinse with water if salt crystals form near electrode tip
- Check for air bubbles in glass bulb by shaking electrode vertically
- Keep glass membrane hydrated for fast response
- Clean terminals with anhydrous alcohol if contaminated
- Regularly clean and calibrate electrode for optimal performance
Lifespan Information: Under normal conditions with proper maintenance, electrodes last over 12 months. Even unused electrodes have a shelf life of 12-24 months if stored correctly. Exposure to strong acids, bases, high temperatures, or corrosive liquids shortens lifespan.
