DETERMINATION OF BENTONITE REQUIREMENT
• Remove cuvette #1 and open the cap. Use the 1000 µL automatic pipette to add exactly 1 mL
of HI83749-0 Bentocheck reagent to the cuvette. For a correct use of the automatic pipette please
follow the related Instruction Sheet.
• Replace the cap. Invert several times to mix and wait for 1 minute.
• Insert the cuvette into the instrument and close the lid. Press READ and “----” will blink on the
display. After a few seconds the instrument displays the first reading. The meter continues updating
the readings until the “Lamp and Read Status” indicator turns off.
• The final displayed value is the averaged reading of turbidity in NTU. This is T2. Record the value.
