Calibration Solution Selection and Parameters
Calibration solutions are used for calibration of conductivity measurement systems. They are all referenced to NIST SRM, come with temperature compensation tables, and meet ISO calibration requirements. Below is a comparison of commonly used calibration solution parameters.
| Order Number | Calibration Value | Volume | Reference Temperature | Reference Standard |
|---|---|---|---|---|
| 50081902 | 74.0 µS/cm | 500 ml | 25 °C | NIST SRM |
| 50081903 | Not specified | 500 ml | 25 °C | NIST SRM |
| 50081904 | 1.406 mS/cm | 500 ml | 25 °C | NIST SRM |
| 50081905 | Not specified | 500 ml | 25 °C | NIST SRM |
| 50081906 | Not specified | 500 ml | 25 °C | NIST SRM |
Key Points for Using Calibration Solutions
- Confirm that the conductivity value of the calibration solution matches the measurement range, and prioritize selecting a standard solution close to the working condition value.
- Check the expiration date before use, avoid contamination, and use as soon as possible after opening.
- Enable the temperature compensation table during calibration to ensure results meet ISO requirements.
- Record the calibration date and order number for traceability.
Selection and Procurement Recommendations
When purchasing spare parts, please verify the order number and equipment model to avoid mixing. Seals are recommended to be replaced in groups according to the maintenance cycle, and calibration solutions should be stored in a cool place.
