Selection and Ordering Recommendations
Select the appropriate seal material and flange standard according to actual working conditions, and regularly calibrate the sensor with calibration solutions.
- Confirm the sensor model and production date (e.g., >20081001).
- Select the O-ring material (CHEMRAZ, VITON, or PTFE) based on medium corrosiveness.
- Verify the flange standard (DN50, ANSI, JIS).
- Select the calibration solution conductivity value according to the measurement range.
