Porous Ceramic Glass pH Electrode 0-14pH Range for Seawater Salt Water with 5m Cable and 0-100℃ Temperature Rating

This porous ceramic glass 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 double salt bridge system with NaNO3 electrolyte solution, specifically designed for seawater and salt water applications with enhanced corrosion resistance.

• 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

• 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; use 3 mol/L KCl storage solution
• Clean terminals with anhydrous alcohol if contaminated; keep connections dry
• 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 thoroughly

With proper maintenance, electrodes typically last over 12 months under normal operating conditions. Unused electrodes maintain a shelf life of 12-24 months when stored properly. Exposure to strong acids, bases, high temperatures, or corrosive liquids may reduce operational lifespan.

• 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
• Regular cleaning and calibration ensures measurement accuracy
