General
Redox potential	146 mV

The Michaelis solution 146 mV is a concentrated redox buffer solution specifically developed for the calibration and testing of redox measuring devices (ORP meters). The manufacturer is Chauvin Arnoux, and the product is packaged in a 125-mL bottle. This solution serves as a reference standard to check and ensure the accuracy of measuring devices in the field of redox potential measurement. The specified redox voltage is 146 mV, corresponding to a defined standard value used in practice for validating measurement systems.

Redox buffer solution
The Michaelis solution 146 mV is a specific buffer solution designed for the calibration of ORP sensors and devices. Redox potential (ORP) is a measure of the oxidizing and reducing capacity of a solution, and precise calibration of measuring devices is essential for reliable results in laboratory and industrial applications. The solution provides a stable reference value of 146 mV, used for setting and checking devices.

Applications
This buffer solution is primarily used in water analytics, process monitoring, and laboratory environments where accurate measurement of redox potential is required. It serves as a calibration standard for devices used in wastewater treatment, drinking water monitoring, or the chemical industry. The use of a standardized solution such as the Michaelis solution 146 mV enables reproducible and comparable measurements across different devices and locations.

Features and equipment in detail
The solution is packaged in a 125-mL bottle designed for safe transport and practical handling. The bottle is suitable for use in laboratory and industrial environments and allows precise dispensing of the required amount. The concentrated form of the solution typically requires dilution according to the device manufacturer’s instructions to achieve the correct calibration value.

Technology explained simply
The Michaelis solution 146 mV is based on a chemical buffer system that maintains a constant redox potential of 146 mV. This value is achieved through the specific composition of the solution and is independent of minor fluctuations in ambient temperature or concentration. The solution serves as a reference to detect deviations in measuring devices and correct them if necessary. Calibration is performed by immersing the ORP sensor in the solution and comparing the displayed value with the target value of 146 mV.

Compatibility and accessories
The Michaelis solution 146 mV is compatible with all ORP measuring devices requiring calibration with a defined redox standard. It can be used in combination with other calibration solutions, such as the Michaelis solution 500 mV or 800 mV, to cover a broader calibration range. Use is according to the instructions of the respective measuring device manufacturer.

Mounting and installation
The solution requires no mounting or installation. It is taken directly from the bottle and placed into a suitable container or directly into the measuring device, depending on the device manufacturer’s instructions. The bottle is designed to protect the solution during transport and storage.

Advantages in operation
The use of the Michaelis solution 146 mV ensures high measurement accuracy and reproducibility. The standardized concentration and defined redox value enable quick and reliable calibration. The 125-mL packaging provides sufficient quantity for multiple calibrations, making device maintenance more efficient. The solution is designed for use in professional environments and supports compliance with quality standards in analytics.
