The XRGST1 pH/T combination electrode from Chauvin Arnoux is a single-stem measurement chain for simultaneous detection of pH value and temperature in field and laboratory applications. It features a 3 m long cable and is specifically designed for use with the CA 10101 measuring instrument. The electrode enables precise and reliable measurements in various application areas where simultaneous determination of pH value and temperature is required, for example in water analysis, the food industry, or chemical process monitoring.

pH/T combination electrode
The XRGST1 is a combined electrode integrating pH and temperature measurement in a single component. This reduces the number of required sensors and simplifies installation and maintenance. The pH measurement is performed via a glass electrode, which is sensitive to changes in hydrogen ion concentration. Temperature measurement is carried out by an integrated temperature sensor that detects the ambient temperature of the measuring medium. This combination enables correct pH value compensation, as the pH value is temperature-dependent.

Application areas
The electrode is designed for use in laboratory and field environments. It is suitable for applications requiring continuous or discrete measurement of pH value and temperature. Typical application areas include monitoring of wastewater treatment plants, quality control in food production, process control in the chemical industry, and environmental analysis. The robust design ensures reliable operation even under demanding conditions.

Functions and equipment in detail
The XRGST1 features a 3 m long cable, allowing flexible positioning of the measurement point without requiring the measuring instrument to be placed directly at the measurement site. The cable is designed for industrial environments and provides sufficient mechanical stability. The electrode itself is designed as a single-stem measurement chain, enabling simple handling and installation. The integrated temperature measurement supports accurate pH value determination, as pH measurement is temperature-dependent and compensation is necessary to avoid measurement errors.

Technology explained simply
The pH measurement is based on the electrochemical reaction at the glass electrode, which generates a voltage proportional to the hydrogen ion concentration in the medium. Temperature measurement is performed by an integrated sensor that detects the temperature of the measuring medium. These data are transmitted via the 3 m long cable to the CA 10101 measuring instrument, where they are processed and displayed. Combining both measurement parameters in one device increases efficiency and reduces error susceptibility caused by separate measurements.

Compatibility and accessories
The XRGST1 is specifically developed for use with the CA 10101 measuring instrument from Chauvin Arnoux. The electrode is not intended for use with other devices unless compatibility is explicitly stated in the technical data of the respective device. Use with other devices is not recommended, as it may lead to measurement errors or damage.

Installation and mounting
Mounting of the XRGST1 is performed by simply immersing the electrode into the medium to be measured. The 3 m long cable allows flexible positioning of the measurement point. The electrode should be installed in an area representative of the entire medium, avoiding direct influences from flows or temperature fluctuations. Connection to the CA 10101 measuring instrument is made via the cable connector plug, specifically designed for this device.

Advantages in operation
The combination of pH and temperature measurement in one electrode reduces the number of required sensors and simplifies installation. The 3 m cable length allows flexible positioning and reduces the need to place the measuring instrument directly at the measurement site. Precise temperature measurement supports accurate pH value determination, increasing the reliability of measurement results. The robust design ensures long service life and reliable operation in various application areas.
