Good Laboratory Practices
for taking Turbidity Measurements
- Avoid samples containing air bubbles, coarse debris, or floating sedimentsall of these can cause erroneous readings.
- For the highest accuracy, calibrate your turbidity meter with the appropriate calibration standard in each measuring range.
- Etched, scratched, or dirty sample vials scatter light and give inaccurate readings; always use clean tubes that have a protective case or extra long tubes to allow for handling outside the measuring area.
- Wear latex or rubber gloves to avoid smudges or fingerprints on vial surface, and to help keep the surface clean.
- Take readings on smooth sturdy surfacesvibration can causes errors in your readings.
