Horiba ORP Standard Solution 225 mV (514-ORP-225)

Horiba ORP Standard Solution 225 mV, 14 mL × 6 (514-ORP-225)

The Horiba ORP Standard Solution 225 mV (Model 514-ORP-225) is a ready-to-use oxidation–reduction potential (ORP) calibration solution supplied in six individual 14 mL bottles. Horiba formulates this solution to provide a stable and precise ORP reference value of +225 mV at 25 °C, supporting accurate calibration and verification of ORP meters and electrodes.

The single-use bottle format helps maintain solution integrity by reducing contamination and exposure to air, which is critical for reliable ORP calibration. Users can perform quick and consistent ORP checks without preparing solutions, making this product ideal for routine calibration, field use, and portable instruments such as Horiba LAQUAtwin ORP meters.

This ORP standard solution suits laboratory testing, water and wastewater monitoring, environmental analysis, and educational applications where reliable redox potential measurement is required.
