Hanna HI4114 Potassium Combination Ion Selective Electrode

Hanna HI4114 Potassium Combination Ion Selective Electrode

The Hanna HI4114 Potassium Combination Ion Selective Electrode is a polymer membrane combination ion-selective electrode (ISE) developed for the accurate measurement of potassium ions in aqueous solutions. With a broad measurement range, wide pH tolerance, and robust build, this electrode is ideal for both laboratory and field applications across environmental, agricultural, and industrial sectors.

Features

• Potassium-Sensitive Polymer Membrane: Offers high selectivity and stable readings for potassium ion detection across varied concentrations.

• Integrated Combination Design: Combines the reference and sensing components in a single body, simplifying usage and maintenance.

• Wide Measurement Range: Detects potassium concentrations from 1M to 1×10⁻⁶M (39,100 to 0.039 ppm), ideal for both high and trace-level detection.

• Broad pH Compatibility: Operates effectively across a pH range of 1.5 to 12.0, allowing use in diverse sample types.

• Durable and Chemically Resistant: Constructed from high-quality PEI and PVC materials for long-lasting reliability under routine lab or field use.

• Standard Connectivity: Equipped with a 1-meter coaxial cable and BNC connector for compatibility with most ion meters and pH meters.

• Stable Response: Positive slope of approximately +56 mV per decade ensures fast, linear response to potassium ion concentrations.
