| 71307106 | EPDM rubber gasket | EPDM | CLS82D/E-**NA*, CLS82D/E-**NB* |
| 71307107 | Silicone gasket | Silicone | CLS82D/E-**NA*, CLS82D/E-**NB* |
Selection Recommendations: Fluororubber (FKM) has excellent oil and chemical resistance; EPDM rubber is resistant to water, steam, and polar solvents; silicone gaskets have a wide temperature range and are suitable for the food and pharmaceutical industries. Please choose the appropriate material according to the actual medium and temperature.
Key Points for Selecting Calibration Solutions and Gaskets
- Calibration solution: Choose a conductivity value close to the measurement point according to the sensor range, and give priority to models with clearly marked values (such as 74.0 µS/cm or 1.406 mS/cm).
- Traceability requirements: All calibration solutions are traceable to NIST SRM, meeting ISO calibration specifications, suitable for quality system audit scenarios.
- Gasket material: FKM is suitable for highly corrosive and high-temperature oil conditions; EPDM is suitable for water treatment and steam environments; silicone is suitable for sanitary applications.
- Compatibility: The gasket kits are only suitable for CLS82D/E-**NA* and CLS82D/E-**NB* sensors. Please check the sensor nameplate before purchasing.
Procurement and Maintenance Recommendations
It is recommended to stock calibration solutions in advance according to the calibration cycle and regularly check the aging of gaskets. When replacing gaskets, please also clean the sensor surface to avoid residual media affecting measurement accuracy.
