FAQs of Conductivity Standard:

Q: How should I use the Conductivity Standard for calibrating a conductivity meter?

A: To calibrate your conductivity meter, pour an appropriate amount of solution into a clean calibration vessel. Immerse the sensor and follow your equipments calibration procedure at 25C. Rinse the sensor with deionized water between calibrations to avoid contamination.

Q: What makes this conductivity standard reliable for laboratory calibration?

A: Each batch is prepared using high-purity KCl and deionized water, strictly following ASTM D1125 practices. Its traceable to NIST standards and a Certificate of Analysis with batch number and traceability is provided, ensuring consistent, accurate results.

Q: When should I replace my Conductivity Standard solution?

A: Always use the solution before its expiry date, which can be found on the bottle label. The shelf life ranges from 12 to 24 months. Discard any solution that appears contaminated, cloudy, or has surpassed its expiry date.

Q: Where should I store the Conductivity Standard to maintain its accuracy?

A: Store the solution in a tightly sealed container at room temperature (between 10C and 40C), away from direct sunlight or strong chemical vapors. This preserves the stability and accuracy of the solution until the stated expiry date.

Q: What is the benefit of the solution being traceable to NIST standards?

A: NIST traceability guarantees that the solutions conductivity value is linked to a recognized, internationally accepted reference. This ensures accuracy, consistency, and acceptance of your calibration results worldwide.

Q: Is the Conductivity Standard safe to handle in a laboratory setting?

A: Yes, it is non-hazardous under typical conditions and contains an aqueous solution of potassium chloride and deionized water. For additional guidance, you may refer to the MSDS provided.
