Hanna HI4015 Silver/Sulfide Half-Cell Ion Selective Electrode

Hanna HI4015 Silver/Sulfide Half-Cell Ion Selective Electrode (ISE)

The Hanna HI4015 Silver/Sulfide Half-Cell Ion Selective Electrode is a solid-state half-cell ion selective electrode (ISE) specifically designed to measure silver (Ag⁺) or sulfide (S²⁻) ion concentrations in a wide variety of samples. This durable, epoxy-bodied electrode serves both as a direct measurement tool and as an indicator electrode in titrations, especially those involving silver nitrate. Its broad chemical compatibility and robust design make it ideal for laboratories, industrial settings, and environmental fieldwork.

Key Features

• Dual Ion Measurement Capability: The HI4015 allows accurate measurement of both silver ions (Ag⁺) and sulfide ions (S²⁻), making it highly versatile for multiple applications.

• Broad Detection Range:

  • For Ag⁺: 1.0 M to 1×10⁻⁶ M (107,900 to 0.11 ppm)

  • For S²⁻: 1.0 M to 1×10⁻⁷ M (32,100 to 0.003 ppm)
    This extensive range enables precise detection across high and trace concentrations.

• Solid-State Half-Cell Design: Built with a stable solid sensing element, the electrode maintains consistent performance over time and resists chemical interference.

• Optimized pH Operating Windows:

  • Ag⁺: pH 2 to 8

  • S²⁻: pH 12 to 14
    This separation helps avoid cross-interference and ensures accuracy in specific conditions.

• High Temperature Tolerance: With a usable temperature range from 0 to 80°C, the electrode performs reliably in both ambient and elevated conditions.

• Rugged Epoxy Body: The chemically resistant epoxy construction ensures durability in demanding field or lab environments.

• BNC Connector for Easy Integration: The 1-meter coaxial cable terminates in a BNC connector, allowing simple connection to most ion meters and titration systems.
