The BPT1-BNC is a redox measuring electrode from the manufacturer Chauvin Arnoux, specifically designed for measuring redox potentials in chemical solutions. It consists of a glass rod, whose lower end is fitted with a platinum wire, serving as the active measuring surface. The electrode features a BNC connector, enabling a secure and standardized connection to suitable measuring instruments. This measuring electrode, also referred to as a metal electrode, responds to changes in the oxidation-reduction potential of the sample and is used together with a reference electrode to achieve precise measurement values.

Applications
The BPT1-BNC is particularly suitable for applications involving highly oxidizing solutions containing chloride. It is recommended for redox titrations as well as for measurements where the service life of the measuring electrode is significantly shorter than that of the reference electrode. In such cases, a separate measuring electrode is advantageous to optimize maintenance and replacement intervals. The use of platinum as the material for the measuring surface ensures high chemical resistance and reliability in aggressive media.

Functions and Equipment in Detail
The electrode consists of a robust glass body, which protects the platinum wire and provides a stable geometric shape. The platinum wire serves as the measuring electrode, directly contacting the solution to be measured. Reactions on the surface of the platinum enable the detection of the redox potential. The BNC connector ensures a mechanically secure and electrically reliable connection to the measuring device. The design is intended for laboratory and industrial applications, particularly in environments with high chemical stress.

Technology Explained Simply
The BPT1-BNC measures the redox potential, i.e., the measure of the oxidizing or reducing power of a solution. To do this, the electrode is immersed in the sample and connected to a reference electrode. The voltage difference between the two electrodes is measured and indicated as the redox potential. The material platinum is crucial here, as it is chemically inert and does not react with most solutions, thereby increasing measurement accuracy. The BNC connector is a standardized plug connector commonly used in measurement technology to ensure secure and interference-free signal transmission.

Compatibility and Accessories
The connection is made via the BNC connector, which is compatible with corresponding inputs on measuring instruments. Two ordering variants for connectors are available to ensure compatibility with different devices. The exact selection of the variant depends on the measuring device being used.

Mounting and Installation
Installation is performed by immersing the electrode in the solution to be measured. The BNC connector is connected to the measuring device. It must be ensured that the measuring surface (platinum wire) is fully immersed in the solution and that no air bubbles adhere to the surface. The electrode should be cleaned before use to avoid measurement errors. The use of a reference electrode is essential to form a complete measuring system.

Advantages in Operation
The use of platinum as the measuring material provides high chemical resistance, especially in oxidizing and chloride-containing solutions. The BPT1-BNC enables precise and reproducible measurement of the redox potential. The separation of measuring electrode and reference electrode reduces replacement requirements, as the measuring electrode can be replaced when worn or contaminated without damaging the reference electrode. The BNC connector ensures a reliable and standardized connection, which is established in many laboratory environments.
