The REDOX buffer solution from Chauvin Arnoux is a specially developed calibration solution for metal electrodes in measurement technology. It is used for precise setting and verification of redox potentials (ORP) in laboratory and industrial applications where high measurement accuracy is required. The solution is ready to use and is supplied in a 125-ml bottle designed for safe transport and practical handling.

Applications

The buffer solution is designed for calibration and fine adjustment of metal electrodes used in water analysis, environmental technology, or chemical process monitoring. It enables reproducible and reliable calibration of measuring instruments to avoid systematic deviations in measurement results. The application is in environments where redox potential values play a decisive role in process control.

Functions and Equipment in Detail

The solution has a defined REDOX potential (ORP) of 468 mV at a temperature of 25 °C, with deviation within a narrow tolerance range of ± 0.02. This high precision ensures consistent calibration and minimizes error sources in measurement value determination. The solution is immediately ready for use, without requiring additional dilution or preparation.

Technology Explained Simply

The redox potential (ORP) is a measure of the oxidizing and reducing capacity of a solution. It is expressed in millivolts (mV) and is crucial for evaluating chemical activity in aqueous media. The buffer solution provides a stable reference value used to verify the accuracy of measuring instruments. The specification “± 0.02” refers to the maximum deviation of the measured potential from the target value of 468 mV, indicating very high stability and reliability of the solution.

Compatibility and Accessories

The REDOX buffer solution is suitable for all measuring systems that use metal electrodes for ORP determination. It is specifically developed for calibration of these electrodes and can be used in conjunction with pH meters, redox meters, or combined ion measurement systems.

Mounting and Installation

The solution requires no mounting or installation. It is taken directly from the packaging and added to the measuring device or calibration setup. Handling is performed under normal laboratory conditions; no special preparation or cleaning steps are required.

Advantages in Operation

The immediate readiness of the solution reduces effort during calibration and increases efficiency in daily operations. The long shelf life of 24 months before opening and a usability period of up to 3 months after opening ensure flexible use and minimize consumption of replacement solutions. The high precision of the REDOX potential ensures reliable measurement results over extended periods.

Scope of Delivery

The scope of delivery includes 1 x REDOX buffer solution in a 125-ml bottle. The solution is available as a single product and is intended exclusively for calibration of metal electrodes.
