• Insert the cuvette into the instrument and press

the Read key. Record the reading.

• Open the instrument lid, slightly rotate the

cuvette and take a new reading.

• Repeat the last step until you read the lowest

NTU value.

• Alternatively, keep the Read key pressed to

make continuous readings. After the first value

is displayed, open the lid and start rotating the

cuvette until the lowest NTU value is displayed.

• Mark this position on the thicker white band on

the top of the cuvette with a water resistant

pencil.

• Always use this position to align it with the

sign on the instrument top.

In order to match multiple cuvettes follow the next

steps:

• Fill some cuvettes with high quality water

(<0.1NTU) up to the 10 mL mark.

• Clean and oil the cuvettes as described before.

MATCHING MULTIPLE CUVETTES

Precise measurements require the use of a single cuvette. If it is not possible, cuvette selection

and matching must be performed before taking measurements.
