Professional deionized water pH sensor designed for pure water applications including RO water and deionized water systems. Features polypropylene housing for chemical resistance and reliable performance in demanding industrial environments.

Based on the Nernst equation principle, this potentiometric sensor functions as a galvanic cell converting chemical reaction energy into electrical energy. The system consists of measuring and reference half-cells with Ag/AgCl reference system and PTFE liquid junction for stable performance in pure water applications.

• 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
• 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 aged electrodes with 10% HCl solution for optimal performance

Typical lifespan exceeds 12 months with proper maintenance. Shelf life of 12-24 months when stored correctly. Regular calibration using fresh pH/ORP standard buffer solutions ensures measurement accuracy throughout the product lifecycle.
