The conductivity reference material from Chauvin Arnoux is a high-precision standard solution specifically developed for the calibration of conductivity measuring instruments. It serves as a reliable reference for checking and calibrating measuring instruments in laboratory and industrial applications, where high accuracy and reproducibility of measurement values are required. The solution is ready-to-use and supplied in a 125-ml bottle, accompanied by an official certificate confirming traceability to the NIST standard.

Applications
This reference material is suitable for all applications requiring calibration of conductivity measuring instruments. These include laboratory environments, quality control processes in the food industry, water analysis in environmental technology, and process monitoring in the chemical industry. The high accuracy and traceability to the NIST standard make it a trustworthy calibration standard for precise measurements.

Features and Equipment in Detail
The solution has a conductivity of 133 µS/cm at a temperature of 20 °C and 147 µS/cm at 25 °C. These values are within a deviation of ± 1 %, ensuring high measurement accuracy. The solution is ready for immediate use, requiring no additional dilution or preparation. The packaging consists of a 125-ml bottle that safely and hygienically stores the solution.

Technology Explained Simply
Conductivity is a measure of a liquid’s ability to conduct electric current. In practice, it is used to assess the ion concentration in water or other liquids. The reference material simulates a defined conductivity that serves as a reference value to check the accuracy of measuring instruments. Traceability to the NIST standard means that calibration is based on internationally recognized standards, ensuring the comparability and global acceptance of measurement results.

Compatibility and Accessories
The reference material is universally applicable for all conductivity measuring instruments requiring calibration with a standard solution of 147 µS/cm at 25 °C. It is specifically designed for use in laboratory and industrial applications where measurement accuracy is critical. The solution is not specific to any particular device or brand, but serves as a general calibration standard.

Installation and Mounting
The solution requires no mounting or installation. It is taken directly from the bottle and placed into the measuring instrument to perform calibration. Use follows the instructions of the respective measuring device, with the solution serving as a reference point to check measurement accuracy.

Operational Advantages
Using this reference material ensures high measurement accuracy and reproducibility. Traceability to the NIST standard increases the reliability of results and facilitates validation in certified environments. The long shelf life of up to 24 months before opening and a shelf life of 3 months after opening ensures flexible use without the need for frequent replacement. The included certificate documents quality and traceability, which is important for quality management and audit processes.

The product is supplied in a 125-ml bottle, accompanied by an official certificate. The delivery includes 1 x conductivity reference material 125 ml and 1 x certificate.
