INSTRUCTIONS
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.
SIGNIFICANCE AND USE
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).

Note: Any damaged or defective item must be returned in
its original packing materials.
CHEMICAL REACTION
• Add to the other vial deionized water up to the 10 mL
mark. Replace the cap and shake to mix.
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 manganese.
• Remove the cap and add 1 packet of HI 93757-0
reagent. Replace the cap and mix.
REFERENCES
The reaction between ozone and the reagent causes a pink
tint in the sample which is proportional to the ozone
concentration.
Adaptation of the EPA recommended DPD method 330.5.
HEALTH AND SAFETY

• Wait for 2 minutes to allow reaction to
occur. This is the reacted sample.

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.
• 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
