Product Overview
This NIST-traceable 13250 µS/cm conductivity standard solution is designed for high-precision calibration of laboratory conductivity meters and electrodes. Formulated with ultra-pure reagents, it ensures consistent and reliable measurements, eliminating errors caused by solution degradation or contamination. The certified reference material grade guarantees compliance with international standards, making it ideal for research, industrial, and educational laboratories. Each batch undergoes rigorous testing to verify accuracy, with a stated uncertainty that meets metrological requirements. The stable formulation resists microbial growth and maintains its conductivity value over extended periods when stored properly. Compatible with most conductivity meters, this standard solution provides a trusted baseline for instrument validation, ensuring your measurements remain traceable to NIST standards. The 500 ml pack size offers an optimal balance between usability and shelf life, reducing the need for frequent replacements while maintaining freshness. Whether used for routine calibration or critical quality control, this conductivity standard delivers the precision demanded by modern laboratory practices.
FAQs
1. What is the shelf life of this conductivity standard?
The shelf life is typically 12 months from the date of manufacture when stored unopened at room temperature, away from direct sunlight.
2. Can this standard be used with any conductivity meter?
Yes, it is compatible with most conductivity meters, provided they are designed to measure solutions within this conductivity range.
3. How should this standard be stored to maintain accuracy?
Store the bottle tightly sealed at room temperature (15-25°C) in a dry, clean environment to prevent contamination or evaporation.
4. Is this standard suitable for field testing?
While primarily designed for lab use, it can be used in field applications if protected from temperature fluctuations and contamination.
5. What alternatives are available for lower conductivity ranges?
Lower-range conductivity standards (e.g., 1413 µS/cm or 12.88 mS/cm) are available for calibration at different measurement levels.
