To ensure your dry standard's accuracy without comparing it to a formazin standard: 1.Manufacturer Calibration: Use a dry standard pre-calibrated and matched to your specific turbidity meter. 2. Regular Verification: Periodically compare it to a trusted wet standard, like formazin, using a calibrated device. 3. Proper Handling: Keep the standard clean, free from scratches or fingerprints, and store it in its protective case. 4. Environmental Consistency: Use the standard under recommended conditions to prevent variability. 5. Unit-Specific Use: Only use the standard with the turbidity meter it was calibrated for. 6. Documentation: Retain calibration certificates for traceability and ensure periodic re-certification by the manufacturer if needed. This approach maintains reliable measurements over time.
