Ozone is an oxidizing agent and a germicide. It is used for
oxidation of organic matter, which produces color or odor in
drinking water.
Note: mg/L is equivalent to ppm (parts per million).

READ THE ENTIRE INSTRUCTIONS BEFORE USING THE KIT
• Use the pipette to fill each glass vial with
5 mL of sample (up to the mark).
5 mL
• Insert one of them into the left hand opening of the
checker disc. This is the blank.
• Add to the other vial deionized water up to the 10 mL
mark. Replace the cap and shake to mix.
• Remove the cap and add 1 packet of HI 93711-0
reagent. Replace the cap and mix.
• Wait for 2 minutes to allow reaction to
occur. This is the reacted sample.
• Remove the cap and insert the
reacted sample into the right
hand opening of the checker
disc.
• Hold the checker disc so that a
light source illuminates the
samples from the back of the
windows.
• Keep the checker disc at a distance of 30-40 cm (1216") to match the color. Rotate the disc while looking at
the color test windows and stop when you find the color
match. Read the value in the result window directly in
mg/L (or ppm) of Ozone.
For best results: Perform the reading three times and
take the average value (divide by 3 the sum of the
three numbers). Intensely colored samples will make
the color matching difficult and they should be
adequately treated before performing the test. Suspended matter in large amounts should be removed
by prior filtration.
Caution: Ultraviolet radiation may cause fading of colors.
When not in use, keep the disc protected from light,
in a cool and dry place.
Interferences: chlorine, bromine, iodine and oxidized man-
ganese.
