Horiba Calcium Ion Standard Solution 1.25 mmol/L

Horiba Calcium Ion Standard Solution 1.25 mmol/L, 25 mL × 2 (Y052L)

The Horiba Calcium Ion Standard Solution 1.25 mmol/L (Model Y052L) is a ready-to-use calibration solution designed for accurate calibration and verification of calcium ion (Ca²⁺) meters and ion-selective electrodes using molar concentration units. Horiba formulates this solution to deliver a stable and precise calcium concentration of 1.25 mmol/L, supporting reliable low-range calcium measurements.

Supplied in two 25 mL bottles, this format provides sufficient volume for repeated calibrations while maintaining solution integrity. Users can perform calibration directly without dilution or additional preparation, which improves consistency and reduces handling errors in both laboratory and field environments.

This standard solution is compatible with Horiba calcium ion meters and LAQUAtwin calcium sensors, and is suitable for applications that require calcium measurement expressed in mmol/L, such as water hardness studies, environmental monitoring, and laboratory education.
