Key Parameter Interpretation
- Order Number: Unique identifier for procurement and inventory management.
- Description: Includes conductivity value, volume, reference temperature, and certification information. Some models do not specify the exact conductivity value, so attention is needed during selection.
- Recommended: Grade A indicates recommended use, usually high precision or commonly used specifications.
- Tk, Position, Group, Valid: Specific data is not provided in the original table; it is recommended to refer to the latest official documentation.
Selection Notes
- Confirm the required conductivity value: such as 74.0 uS/cm or 1.406 mS/cm, select according to the measurement range.
- Check certification requirements: All calibration solutions refer to NIST SRM and come with temperature tables, meeting ISO-compliant calibration.
- Note the volume: All are 500 ml packaging, suitable for laboratory or on-site calibration.
- Reference temperature: Uniformly 25°C to ensure temperature compensation consistency.
Frequently Asked Questions
How should calibration solutions be stored?
They should be sealed and stored in a cool, dry place, avoiding direct sunlight. Check the expiration date before use and ensure the temperature is close to the reference temperature of 25°C.
Can they be used with other conductivity meters?
These calibration solutions are versatile, but it is recommended to prioritize matching with CLS21D or similar conductivity measurement systems. Confirm compatibility before use.
