TURBIDITY RANGE

When taking turbidity measurements, several basic rules should be followed:

• Always use cuvets without scratches or cracks because they can cause inaccurate readings.

• Always cap the cuvets to avoid spillage of the sample into the instrument.

• Always close the lid of the instrument during measurement.

• Do not use too much oil to prevent contamination of the optical system.

To take turbidity measurements, follow the next steps:

• Turn the instrument ON by pressing ON/OFF.

When dashes are displayed on the LCD, the

instrument is ready. The current time appears on

the upper left corner of the display and the

range name appears on the lower right corner.

• Fill a clean, dry cuvet with 10 mL of sample up to the

mark, taking care to handle the cuvet by the top.

• Replace the cap.
