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 reference point for checking and calibrating measuring devices in laboratory and industrial applications, where reliable and reproducible measurement values are crucial. The solution is ready-to-use and meets high requirements for accuracy and stability.

Applications
This reference material is used in applications requiring the calibration of conductivity measuring instruments, for example in water analytics, process monitoring, or quality control. It is particularly suitable for environments where traceability of measurement values to an internationally recognized standard is required. The material is used directly from the packaging, without additional preparation or dilution.

Features and Equipment in Detail
The solution has a conductivity of 1274 µS/cm at a temperature of 20 °C and 1408 µS/cm at 25 °C. These values are defined with a deviation of ± 1 %, ensuring high measurement accuracy. Traceability to the NIST standard (National Institute of Standards and Technology) ensures international recognition and comparability of measurement results. The solution is packaged in a 125-ml bottle and is delivered with an official certificate confirming the specific characteristics and traceability.

Technology Explained Simply
Conductivity describes the ability of a liquid to conduct electric current and is an important parameter in water analytics. The specified values at 20 °C and 25 °C account for the temperature dependence of conductivity, as it increases with rising temperature. The deviation of ± 1 % defines the tolerance range within which the actual conductivity of the solution lies. Traceability to the NIST standard means that the calibration of the solution can be traced back to an official reference, which is crucial for the validity of measurement results in scientific and industrial contexts.

Compatibility and Accessories
The reference material is suitable for all conductivity measuring instruments requiring calibration with a standard solution. It is not specific to any particular device or brand, but serves as a universal calibration standard. It is used directly from the bottle, without requiring additional accessories such as diluents or measuring cells.

Mounting and Installation
The solution requires no mounting or installation. It is taken directly from the packaging and used in the measuring device to perform the calibration. The bottle is designed to dispense the content without contamination or loss.

Operational Advantages
The ready-to-use form of the solution reduces preparation effort and minimizes sources of error. The long shelf life of up to 24 months before opening and stability of 3 months after opening allows for flexible use. The included certificate documents the specific characteristics and traceability, which is important for quality management systems and audit requirements. Using a NIST-traceable standard increases the reliability of measurement results and facilitates validation in certified environments.

Scope of Delivery
The product is delivered in a 125-ml bottle, together with an official certificate confirming the specific characteristics and traceability. The scope of delivery therefore includes 1 x conductivity reference material 125 ml and 1 x certificate.
