Selection and Usage Points
When purchasing and using CLS16E calibration solutions, the following key points should be noted to ensure the validity of calibration results.
Key Precautions
- Traceability and Compliance: All calibration solutions are traceable to NIST SRM and come with temperature compensation tables, meeting ISO requirements for conductivity measurement system calibration.
- Concentration and Range Matching: 50081902 is 74.0 µS/cm, suitable for low conductivity ranges; 50081904 is 1.406 mS/cm, suitable for medium to high conductivity ranges. Other models do not indicate specific conductivity values, so selection should be confirmed based on the instrument range.
- Recommendation Level: All spare parts have a recommendation level of A, indicating preferred selection.
- Packaging Specification: All are 500 ml bottles, convenient for laboratory or on-site calibration use.
- Reference Temperature: The reference temperature for all calibration solutions is 25°C; temperature compensation should be noted during calibration.
Recommended Calibration Operation Steps
- According to the conductivity range to be measured, select the calibration solution with the appropriate order number from the spare parts list.
- Check the expiration date and packaging integrity of the calibration solution to ensure it is unopened and within the expiration date.
- Thoroughly clean and dry the conductivity sensor to avoid cross-contamination.
- Immerse the sensor in the calibration solution, ensuring the sensitive part is fully submerged and avoiding bubble attachment.
- After the reading stabilizes, check the temperature compensation table based on the calibration solution temperature, perform temperature compensation, or directly input the reference temperature.
- Complete calibration according to the instrument operation manual and record the calibration results.
Frequently Asked Questions (FAQ)
Can CLS16E calibration solution be reused?
Reuse is not recommended. After contact with the sensor, the calibration solution may become contaminated, causing changes in conductivity value and affecting calibration accuracy. It is recommended to use fresh calibration solution for each calibration.
How should calibration solution be stored?
Calibration solution should be stored in a cool, dry, and dark place, avoiding extreme temperatures. After opening, it should be sealed and used as soon as possible. For specific storage conditions, please refer to the product label or instructions.
Can calibration solution still be used after expiration?
No. The conductivity value of expired calibration solution may drift, and traceability accuracy cannot be guaranteed. Please be sure to use within the expiration date and regularly check inventory.
