A redox buffer solution 475 mV ± 5 mV (25 °C), 250 ml is used for calibration and verification of redox (ORP) measuring devices. It provides a defined reference potential used to check or adjust the accuracy of a redox electrode. It is used: To adjust a redox measuring device so it displays correct mV values. To regularly check the electrode function (detecting drift or contamination). Typical applications where redox potential is measured include drinking water and wastewater monitoring, swimming pool technology, aquaristics, environmental analysis, and industrial processes. The value of 475 mV lies in the medium oxidation range and is suitable for systems with moderate oxidation potential. What do the specifications on the bottle mean? 475 mV This is the target redox potential of the solution at 25 °C. ± 5 mV This is the tolerance. The actual value lies between 470 mV and 480 mV. (25 °C) The specified value applies exactly at 25 °C because redox potential depends on temperature. 250 ml This is the filling volume of the bottle. The larger quantity is suitable for frequent calibrations or regular use in laboratories or industrial environments. The solution is used to precisely calibrate or check a redox measuring device in the medium mV range, where 475 mV at 25 °C is the defined reference value with an accuracy of ± 5 mV.

What is a Redox Buffer Solution Used For? A redox buffer solution 475 mV ± 5 mV (25 °C), 70 ml is used for the calibration and verification of redox (ORP) measuring devices that measure the oxidation or reduction potential of a solution. It is used for: Adjusting a redox measuring device so that readings are accurate and reliable. Measurements in laboratories, water treatment, environmental analysis, or industrial processes where the redox state is monitored. Particularly suitable for regular checking of the measuring electrode. A value of 475 mV typically corresponds to a moderately oxidizing system, e.g., lightly chlorinated water or weakly oxidizing solutions. What Do the Details on the Bottle Mean? 475 mV This is the target value of the redox potential at 25 °C. The solution is chemically stable to provide exactly this value. ± 5 mV This is the tolerance or accuracy. The actual redox value is at most 5 mV above or below 475 mV (i.e., between 470 mV and 480 mV). This ensures precise calibration. (25 °C) The value applies exactly at 25 °C, as the redox potential is temperature-dependent. Many devices account for this via temperature compensation. 70 ml This is the filling volume of the solution in the bottle. The solution is used to reliably calibrate a redox measuring device in the medium oxidation range, where 475 mV at 25 °C is the defined reference value with a tolerance of ± 5 mV.
