Measuring Turbidity | ||
You need the Sample Bottle and the Turbidity Tube. The Turbidity
Tube is a plastic tube in two pieces with a black symbol on the
bottom and a scale on the side. The reading may be easier and more
accurate if you use it over a light coloured surface or a sheet
of white paper.

6. Read the value on the tube's scale. Write the value on the data sheet. 7. Rinse the tube. NOTE: lf the reading is above 200 repeat the measurement. Read off how much water is in the tube. Empty the Sample Bottle. Pour the water in the tube in the Sample Bottle. Top up the bottle with the same amount of clear water (if there was 150mL in the tube, there should now be 300mL in the Sample Bottle). Repeat the measurement. Multiply the value by two. |
