Hanna Potassium Combination Ion-Selective Electrode (ISE) - HI4114

The HI4114 Potassium Combination Ion-Selective Electrode is designed for accurate determination of potassium ions (K⁺) in solution, utilizing a liquid PVC membrane with specialized organic ion exchanger technology. The robust polyetherimide (PEI) and PVC body construction ensures durability in laboratory, agricultural, wine, and water analysis applications.

Its skirted cone geometry enhances measurement repeatability in standard laboratory vessels. The HI4114 measures a broad potassium range from 1.0 M to 1 × 10⁻⁶ M (39,100 to 0.039 mg/L), supported by an approximate slope of +56 mV. With a 1 m coaxial cable terminating in a standard BNC connector, it provides excellent connectivity to most modern ion meters and laboratory instruments.

• Utilizes advanced liquid membrane sensor for reliable potassium ion detection.
• Optimized for operation in the pH range from 1.5 to 12.
• Functions efficiently in temperature conditions between 0 and 40 °C.
• Sturdy 120 mm long and 12 mm diameter body allows insertion into standard flasks and beakers.
• Widely applicable in wine, agricultural, environmental, and water quality analyses.

Industrial uses include analytical laboratories, quality control for agriculture and water treatment facilities, and educational research environments where accurate potassium monitoring is required.
