Dissolved Oxygen

• Let the sample stand and the flocculent agent will start to settle.

• After approximately 2 minutes, when the upper half of the bottle becomes

limpid, add 10 drops of HI 93732C-0.

• Replace the cap and invert the bottle until the settled flocculent dissolves completely. The sample is

ready for measurement when it is yellow and completely limpid.

• Fill the cuvette up to the mark with 10 mL of the unreacted (original)

sample, and replace the cap. This is the blank.

• Place the cuvette into the holder and close the lid.

• Press ZERO key. The display will show “-0.0-” when

the meter is zeroed and ready for measurement.

• Remove the cuvette.

• Fill another cuvette up to the mark with 10 mL of the reacted sample and

replace the cap.

• Reinsert the cuvette into the instrument.

• Press READ to start the reading. The instrument will display the results in mg/L of dissolved oxygen.

MEASUREMENT PROCEDURE

• Select the 

Dissolved Oxygen

 method using the procedure described in

the 

Method Selection

 section (see page 12).

• Fill one 60 mL glass bottle completely with the unreacted sample.

• Replace the cap and ensure that a small part of the sample spills over.

• Remove the cap and add 5 drops of HI 93732A-0 and 5 drops of

HI 93732B-0.

• Add more sample, to fill the bottle completely. Replace the cap again

and ensure that a part of the sample spills over. This is to make sure
that no air bubbles have been trapped inside, which could alter the
reading.

• Invert several times the bottle. The sample becomes orange-yellow and a

flocculent agent will appear.
