Hanna HI4014 Potassium Half-Cell Ion Selective Electrode

Hanna HI4014 Potassium Half-Cell Ion Selective Electrode (ISE)

The Hanna HI4014 Potassium Half-Cell Ion Selective Electrode is a high-precision potassium ion selective electrode (ISE) that uses a polymer membrane half-cell design to measure potassium ion (K⁺) concentrations in a wide variety of samples. Whether used in environmental, food, or biological testing, this electrode provides quick, accurate, and reproducible results in both field and laboratory settings.

Key Features

• Wide Detection Range: This electrode detects potassium concentrations from 1.0 M to 1×10⁻⁶ M, which corresponds to 39,100 to 0.039 mg/L (ppm). As a result, it offers exceptional versatility for high and trace-level potassium testing.

• Half-Cell Polymer Membrane Design: As a half-cell ISE, the HI4014 requires a separate reference electrode, giving users more flexibility for advanced analytical setups.

• Extended pH Compatibility: Operating effectively between pH 1.5 and 12.0, the electrode adapts to a broad range of sample types, including acidic and alkaline environments.

• Durable and Field-Ready: Its epoxy/PVC body ensures long-term durability, chemical resistance, and excellent performance under routine or rugged conditions.

• Stable Measurement Across Temperature Range: Designed for use from 0 to 40°C, the HI4014 maintains accuracy in most water, soil, and lab environments.

• Broad Application Scope: This electrode is widely used for testing potassium in wine, natural waters, soil extracts, and biological fluids.

• BNC Connector for Compatibility: The 1-meter coaxial cable terminates in a BNC connector, allowing easy connection to a wide variety of ion meters and analyzers.
