The XPT1-BNC from Chauvin Arnoux is a redox indicator electrode specifically developed for measuring the oxidation-reduction potential (ORP) in chemical solutions. It consists of a platinum wire integrated into a robust PVC body and features a BNC connector as the interface. This electrode serves as a measuring electrode that responds to changes in redox potential, with measurement always performed in combination with a reference electrode. The combination enables determination of the oxidizing or reducing strength of a sample, where the measuring electrode detects the potential reaction and the reference electrode provides a constant reference potential.

Applications

The XPT1-BNC is particularly suitable for highly oxidizing solutions, especially those containing chlorides. It is recommended for applications such as redox titrations, where high stability and chemical resistance of the electrode are required. Due to its construction with a protected platinum rod, it is also suitable for applications where the lifespan of the measuring electrode is significantly shorter than that of the reference electrode, making separate replaceability advantageous.

Functions and Equipment in Detail

The electrode features a PVC body that encases the platinum wire, thus protecting it from mechanical damage. The platinum rod is inert and does not react with the measuring solution, ensuring precise and reproducible measurement of the redox potential. The BNC connector enables a secure and standardized connection with measuring instruments that support this interface. The construction offers higher sealing compared to the XPT2 model, increasing reliability when measuring in aggressive media.

Technology Explained Simply

Redox potential (ORP) measures the ability of a solution to donate or accept electrons – its electron activity. The platinum measuring electrode acts as a sensor detecting the potential reaction in the solution. The measurement is carried out via the potential difference between the measuring electrode and a reference electrode, which provides a constant reference potential. The result is given in millivolts (mV) and allows conclusions about the oxidizing or reducing strength of the sample. The use of an inert metal such as platinum ensures that the electrode is not involved in the chemical reaction itself, but only detects potential changes.

Compatibility and Accessories

The XPT1-BNC is designed for use with reference electrodes used in laboratory or field operations. Combining it with an appropriate reference electrode is essential to ensure accurate ORP measurement. The electrode is suitable for applications in both laboratory and field environments, particularly in settings requiring high chemical resistance and mechanical robustness. The BNC interface is a standard in measurement technology and allows connection to a wide range of measuring instruments.

Mounting and Installation

The electrode is directly immersed into the solution to be measured. The BNC connector is attached to the measuring instrument. It is important that the electrode is fully immersed in the sample to ensure a representative measurement. Installation requires no special tools or additional components; the connection is made via the BNC interface. The electrode is designed for use in laboratory and field environments, with temperature and chemical resistance ensured by the PVC housing and platinum rod.

Operational Advantages

The XPT1-BNC offers high chemical resistance, particularly against oxidizing solutions and chlorides. The robust PVC housing protects the platinum rod from breakage and mechanical damage. The higher sealing compared to the XPT2 model increases measurement reliability. The use of a BNC connector ensures a secure and standardized connection with measuring instruments. The electrode is suitable for applications where separate replaceability of the measuring electrode versus the reference electrode is beneficial, making maintenance and operation more efficient.
