Product Overview

This specialized glass pH electrode operates on the Nernst equation principle, utilizing a galvanic cell system that converts chemical reaction energy into measurable electrical potential. Designed specifically for hydrofluoric acid environments up to 4000ppm concentration, the sensor features a robust double salt bridge system and porous ceramic liquid junction for 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 requirements
  • Flow-Through Installation: Monitor flow velocity and pressure conditions
  • Submersion Installation: Adjust bracket length according to application needs
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
  • Check for air bubbles in glass bulb by shaking electrode vertically
  • Keep glass membrane hydrated for optimal response time
  • Store with 3 mol/L KCl solution in protective cap
  • Clean aged electrodes with 10% HCl solution for cloudy membranes or deposits
  • Regularly clean and calibrate electrode for consistent performance
Lifespan & Calibration

With proper maintenance, electrodes typically last over 12 months in normal 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.

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, proceed with actual sample measurements
Note: Electrodes are consumable items and generally not covered by warranty. Proper maintenance is essential for optimal performance and extended service life.
