The XRV1H-S7 is a pH combination electrode from the manufacturer Chauvin Arnoux, designed for precise pH measurement in various applications. It features a single-stem measuring chain made of a PVC body, equipped with a ceramic junction and a spherical tip. Connection is via an S7 plug, enabling a secure and standardized link to compatible measuring devices. The electrode is suitable for use in laboratory and industrial environments where reliable and low-maintenance pH measurement is required.

Applications
The pH combination electrode XRV1H-S7 is suitable for applications requiring continuous or discrete pH measurement in liquids. Typical applications include process monitoring in the food industry, water treatment, chemical industry, and laboratory environments. The combination of PVC body and ceramic junction ensures good chemical resistance against many liquids, enabling the electrode to be used in a wide range of media.

Functions and Equipment in Detail
The electrode is designed as a single-stem measuring chain, meaning both the measuring and reference electrodes are integrated into one housing. This simplifies handling and reduces the number of required components. The PVC body provides high mechanical stability and resistance to many chemical substances. The ceramic junction serves as an ion exchange point and ensures a stable reference voltage. The spherical tip enables precise and reproducible measurement, especially in liquids with low viscosity. The S7 plug is a standardized connector, enabling a secure and backward-compatible connection to measuring devices from Chauvin Arnoux and other manufacturers.

Technology Explained Simply
The pH combination electrode measures the partial pressure of hydrogen ions in a liquid, expressed as pH value. The single-stem measuring chain combines the functions of measuring and reference electrodes in one housing, simplifying installation and maintenance. The PVC body protects sensitive internal components from mechanical stress and chemical corrosion. The ceramic junction serves as a selective ion transition, which is crucial for measurement stability. The spherical tip ensures an even contact surface with the measuring liquid, increasing measurement accuracy. The S7 plug enables easy and secure connection to compatible measuring devices, allowing the electrode to be quickly integrated into existing systems.

Compatibility and Accessories
The XRV1H-S7 is equipped with an S7 plug, suitable for a wide range of pH measuring devices from Chauvin Arnoux and other manufacturers. The electrode can be used in systems supporting an S7 connection, making it applicable in many industrial and laboratory applications.

Installation and Mounting
Installation of the XRV1H-S7 is performed by simply inserting the S7 plug into the corresponding connection on the measuring device. The electrode is then immersed in the liquid to be measured, ensuring the spherical tip is fully covered. Mounting requires no special tools or additional components. Use is typically in conjunction with a pH measuring device that displays, stores, or transmits the measurement values.

Operational Advantages
The XRV1H-S7 offers reliable and low-maintenance pH measurement thanks to its single-stem design and robust materials. The PVC body and ceramic junction ensure high chemical resistance, extending the electrode’s service life. The spherical tip enables precise measurement, and the S7 plug ensures easy integration into existing systems.
