Component Specifications

Definition
An electrolyte solution used in pH monitoring sensors that contains specific ions (typically potassium chloride or other salts) to maintain stable electrical conductivity between the pH-sensitive glass electrode and reference electrode, ensuring accurate measurement of hydrogen ion concentration in aqueous solutions.
Working Principle
The electrolyte solution creates a stable ionic bridge between the pH-sensitive glass membrane and reference electrode, allowing consistent ion exchange and maintaining a stable reference potential. It facilitates the flow of ions to complete the electrochemical circuit, enabling precise measurement of voltage differences proportional to pH levels.
Materials
Aqueous solution containing potassium chloride (KCl) 3M or 4M concentration, sometimes with silver chloride (AgCl) additives for reference electrodes. May include pH buffers and stabilizers. Typically uses deionized water as solvent.
Technical Parameters
  • pH Range Typically 4-10
  • Container Sealed glass or plastic ampoule
  • Shelf Life 12-24 months
  • Conductivity >100 mS/cm
  • Concentration 3M or 4M KCl
  • Temperature Range 0-80°C
Standards
ISO 10523, DIN 19266, ASTM E70

Frequently Asked Questions

How often should electrolyte solution be replaced in pH sensors?

Typically every 3-6 months depending on usage frequency and environmental conditions. More frequent replacement may be needed in high-temperature or contaminated applications.

Can different electrolyte concentrations be mixed?

No, mixing different concentrations can alter ionic strength and affect measurement accuracy. Always use the manufacturer-specified concentration.

What happens if electrolyte solution dries out in the sensor?

Dried electrolyte causes unstable readings, slow response times, and potential sensor damage. The sensor should be refilled immediately with fresh solution.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
