Note: “—” in the table indicates that the original materials did not provide a specific conductivity value. For selection, please refer to the product label or certificate.
Precautions for Using Calibration Solutions
- All calibration solutions are accompanied by a temperature compensation table for accurate calibration in environments other than 25°C.
- Calibration solutions should be stored in a cool, dark place and used as soon as possible after opening to avoid contamination.
- Select a calibration solution with an appropriate conductivity value according to the measurement range, for example, use 74.0 µS/cm for low-conductivity water samples and 1.406 mS/cm for high conductivity.
Spare Parts Procurement and Maintenance Recommendations
- Check the instrument model and serial number to confirm the required spare parts order number.
- Select the enclosure material (plastic or stainless steel) according to the working conditions.
- If digital integration is required, prioritize the IO-Link upgrade kit.
- Regularly calibrate with NIST-traceable calibration solutions to ensure measurement accuracy meets ISO requirements.
Correct selection of spare parts and calibration solutions can significantly extend the service life of the CLD18 and ensure the reliability of process analysis.
