Product Overview
This 200 µS/cm premium conductivity standard is engineered for high-accuracy calibration of laboratory conductivity meters and sensors. Formulated with ultra-pure reagents and deionized water, it ensures consistent performance with a certified conductivity value of 200 µS/cm at 25°C, traceable to NIST standards. The solution is stabilized to minimize drift over time, providing reliable reference points for routine instrument validation. Its low-temperature coefficient ensures minimal variation across standard lab conditions, while the sealed packaging prevents contamination and evaporation. Designed for immediate use, this standard eliminates the need for time-consuming in-house preparation, reducing procedural errors. The 500 ml pack size offers sufficient volume for repeated calibrations without frequent replacements. Each batch undergoes rigorous quality testing to guarantee compliance with ISO 17034 and ISO/IEC 17025 requirements. The solution’s homogeneous composition ensures uniform conductivity throughout the container, while its extended shelf life maintains stability for up to 24 months when stored properly. Ideal for environments where precision is critical, this conductivity standard delivers reproducible results across multiple instruments and operators.
FAQs
1. What is the shelf life of this 200 µS/cm conductivity standard?
The unopened standard has a shelf life of 24 months from the date of manufacture when stored at room temperature. Once opened, use within 6 months for optimal accuracy.
2. Can this standard be used with all conductivity meter brands?
Yes, this 200 µS/cm standard is compatible with all major conductivity meter brands, including Metrohm, Hanna, and Mettler Toledo, as it adheres to universal calibration protocols.
3. How should I store this conductivity standard to maintain accuracy?
Store the bottle tightly sealed at 15–25°C, away from direct sunlight and sources of contamination. Avoid temperature fluctuations to prevent condensation inside the container.
4. Is this standard traceable to international reference materials?
Yes, the 200 µS/cm value is traceable to NIST (National Institute of Standards and Technology) through an unbroken chain of comparisons, ensuring metrological reliability.
5. What precautions should I take while handling this solution?
Use clean, dry labware to avoid contamination. Always recap the bottle immediately after use to prevent CO₂ absorption, which can alter conductivity over time.
