MEASUREMENT PROCEDURE

• Select the

Free Chlorine

method using the procedure

described in the

Method Selection

section (see page 12).

• Fill the cuvette with 10 mL of unreacted sample (up to the

mark) and replace the cap.

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

Free Chlorine

FREE CHLORINE

10 mL

• Remove the cuvette and add the content of one packet of HI 93716-0

DPD reagent. Replace the cap and shake gently for about 20 seconds to
dissolve most of the reagent.

• Reinsert the cuvette into the instrument.

• Press TIMER and the display will show the countdown prior to the

measurement or, alternatively, wait for 2 minutes and 30 seconds and
press READ. When the timer ends the meter will perform the reading.

• The instrument displays the results in mg/L of bromine.

INTERFERENCES

Interference may be caused by: Chlorine, Iodine, Ozone, Oxidized forms of Chromium and Manganese.
In case of water with hardness greater than 500 mg/L CaCO

, shake the sample for approximately 2

minutes after adding the reagent.
In case of water with alkalinity greater than 250 mg/L CaCO

or acidity greater than 150 mg/L CaCO

the color of the sample may develop only partially, or may rapidly fade. To resolve this, neutralize the
sample with diluted HCl or NaOH.
