Product Overview
This 13400 µS/cm conductivity standard is a high-precision reference solution designed for the calibration and verification of conductivity meters, ensuring accurate and reproducible measurements in laboratory settings. Traceable to NIST (National Institute of Standards and Technology), this standard provides a reliable benchmark for instrument performance, eliminating variability caused by environmental factors or sensor drift. The formulation is chemically stable, resistant to microbial contamination, and optimized for long-term consistency, making it suitable for frequent use in research, industrial, and educational laboratories. Each batch undergoes rigorous quality control to confirm its stated conductivity value, with certification documentation included for compliance with ISO and GLP standards. The solution is pre-mixed and ready to use, eliminating the need for dilution or preparation, which reduces the risk of human error during calibration procedures. Packaged in a durable, leak-proof HDPE bottle, it minimizes exposure to light and air, preserving the integrity of the standard over its shelf life. Whether used for routine maintenance, audits, or troubleshooting, this conductivity standard delivers the accuracy required for critical applications where precision is non-negotiable.
FAQs
1. What is the shelf life of this 13400 µS/cm conductivity standard?
The shelf life is typically 12–24 months from the date of manufacture when stored unopened at room temperature (15–25°C). Always check the label for the exact expiry date.
2. Can this standard be used for both bench-top and portable conductivity meters?
Yes, this standard is compatible with all conductivity meters, including bench-top, portable, and inline systems, provided they operate within the 13400 µS/cm range.
3. Is recalibration required if the bottle is opened multiple times?
Frequent opening can introduce contaminants or evaporation, potentially altering the conductivity. For best results, use the standard within 3 months of opening and reseal tightly after each use.
4. How does NIST traceability benefit my calibration process?
NIST traceability ensures the standard’s conductivity value is verified against a nationally recognized reference, providing documented accuracy and compliance with regulatory or audit requirements.
5. What alternatives are available if I need a lower or higher conductivity range?
Alternatives include standards at 1413 µS/cm, 12.88 mS/cm, or 111.8 mS/cm, depending on your instrument’s measurement range. Always select a standard closest to your typical sample values.
