The sensor features a double salt bridge system and porous ceramic liquid junction for reliable performance in electroplating wastewater applications containing sodium sulfate and heavy metals.
- 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
- Unscrew protective cap and immerse electrode bulb and liquid junction in sample before use
- Rinse with water if salt crystals form near electrode tip due to electrolyte evaporation
- Check for air bubbles in glass bulb by shaking electrode vertically
- Keep glass membrane hydrated for fast response time
- Store with 3 mol/L KCl solution in protective cap
- Clean terminals with anhydrous alcohol if contaminated
- Avoid prolonged immersion in distilled water, protein solutions, or contact with silicone grease
- Clean aged electrodes with cloudy membranes using 10% HCl solution
- 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
- Perform regular calibration and maintenance for optimal performance
Under normal conditions with proper maintenance, electrodes typically last over 12 months. 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 that electrodes are consumable items and generally not covered by warranty.
