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 in laboratory and industrial applications where exact and reproducible measurement results are required. The solution is ready-to-use and supplied in a 125-ml bottle containing an official certificate. The conductivity is 11.64 µS/cm at 20 °C and 12.85 µS/cm at 25 °C, with a deviation of ± 1 %. Traceability is ensured according to the OIML standard, guaranteeing the quality and reliability of the calibration.

Applications
This reference material is primarily used for the calibration and validation of conductivity measuring instruments. It is suitable for applications in water analysis, process control, environmental monitoring, as well as in the chemical and pharmaceutical industries. The precise conductivity enables accurate adjustment and verification of measuring instruments, minimizing systematic errors and ensuring measurement accuracy.

Features and Equipment in Detail
The solution is ready for immediate use without requiring additional dilution or preparation. Packaging in a 125-ml bottle ensures practical handling and minimizes wear. The included certificate documents the specific conductivity values and traceability, which is relevant for quality management and certification processes. The solution is stable for up to 24 months before opening and remains stable for 3 months after opening, enabling flexible use.

Technology Explained Simply
Conductivity is a measure of a liquid’s ability to conduct electric current and is expressed in microsiemens per centimeter (µS/cm). The values at 20 °C and 25 °C account for the temperature dependence of conductivity, which must be considered during measurements. The deviation of ± 1 % ensures the solution remains within a defined tolerance range, which is critical for instrument calibration. Traceability according to OIML (Organisation internationale de métrologie légale) means the calibration can be traced back to international standards, ensuring global comparability and acceptance of measurement results.

Compatibility and Accessories
The reference material is compatible with all conductivity measuring instruments requiring calibration with a standard solution. It is specifically designed for use in laboratory and industrial applications where high accuracy and reproducibility are required. It is used in conjunction with suitable measuring probes and devices capable of measuring and calibrating conductivity. The solution is used directly from the bottle without additional accessories.

Installation and Mounting
No installation or mounting is required, as this is a liquid standard solution. Use involves simply taking the solution from the bottle and applying it to the measuring instrument to be calibrated. The bottle is designed to be opened and used without additional tools or aids.

Operational Advantages
Using the conductivity reference material ensures high measurement accuracy and reproducibility. The ready-to-use format and long shelf life before opening reduce preparation effort. Traceability according to the OIML standard increases the acceptance of calibration in certified environments. The 3-month stability after opening allows flexible use without immediate consumption.

Scope of Delivery
The scope of delivery includes 1 x conductivity reference material in a 125-ml bottle and 1 x official certificate documenting the specific conductivity values and traceability.
