Horiba Ion Standard Solution Potassium (K⁺)

Horiba Ion Standard Solution Potassium (K⁺) 100 mg/L, 500 mL (500-K-SL)

The Horiba 500-K-SL Potassium Ion Standard Solution provides a ready-to-use calibration and verification standard for accurate measurement of potassium ions (K⁺) using ion-selective electrodes and ion meters. Horiba formulates this solution to deliver a stable potassium concentration of 100 mg/L, making it suitable for low-range potassium calibration in laboratory and environmental applications.

This ion standard solution supports routine calibration, instrument performance checks, and analytical method validation for potassium measurements in water, wastewater, and environmental samples. Because the solution comes fully prepared, users can perform calibration directly without dilution, which reduces handling errors and improves measurement consistency.

The 500 mL bottle provides sufficient volume for repeated calibration and verification procedures. The solution fits well in environmental monitoring programs, agricultural analysis, laboratory quality control, and educational settings that require reliable low-level potassium determination.
