Selection and Procurement Recommendations
When purchasing, please confirm the order number of the required spare parts and note that the old material number may be used for compatibility inquiries. For calibration solutions, select the specification with the appropriate conductivity value according to the actual measurement range to ensure calibration accuracy.
- Confirm that the sensor model is CLS21.
- Select spare parts according to maintenance needs: loop socket, seal, or cable connector.
- Select calibration solution according to the measurement range: low conductivity (e.g., 74.0 uS/cm) or high conductivity (e.g., 1.406 mS/cm).
- Check the order number and old material number to avoid incorrect purchase.
