About Our Hydrogen Peroxide Tests with HHWT-12

We offer two different Hydrogen Peroxide tests and they all develop a colorimetric red color by a slow oxidation reaction of hydrogen peroxide (H2O2) with
Iodide to form Iodine. The iodine then reacts instantly with the DPD indicator to form a red color. To speed up the reaction a catalyst, Molybdate salt, is added
in the Low range and Mid Range products.

The Low Range product (HHWT-486616) is buffered to about a pH of 5.0 to 5.5, and the chemistry is essentially complete in 2 minutes at this pH if the water
sample is at room temperature (between 18°C to 22°C). Cold samples (below 14C) will require 4 minutes or more to complete the reaction. Warm samples
(above 23°C) will read about 10% higher. Follow directions as written to get accurate results. For values above 1.8 PPM you should dilute with distilled or
Deionized water and retest.

The Mid range product (HHWT-486648) is buffered to about a pH of 2.1 to 2.4. This slows the catalytic reaction and allows the test to measure higher levels
of hydrogen peroxide. This test is only accurate if your sample is at room temperature and if you follow directions as written.

The High Range product (HHWT-486676) uses no Molybdate catalyst; and therefore the reaction proceeds slowly. This allows for the detection range to be

Hydrogen Peroxide MR Test Procedure

About Our Hydrogen Peroxide Tests with HHWT-12

We offer two different Hydrogen Peroxide tests and they all develop a colorimetric red color by a slow oxidation reaction of hydrogen peroxide (H2O2) with

Iodide to form Iodine. The iodine then reacts instantly with the DPD indicator to form a red color. To speed up the reaction a catalyst, Molybdate salt, is added

sample is at room temperature (between 18°C to 22°C). Cold samples (below 14C) will require 4 minutes or more to complete the reaction. Warm samples
(above 23°C) will read about 10% higher. Follow directions as written to get accurate results. For values above 1.8 PPM you should dilute with distilled or
Deionized water and retest.

The Mid range product (HHWT-486648) is buffered to about a pH of 2.1 to 2.4. This slows the catalytic reaction and allows the test to measure higher levels

of hydrogen peroxide. This test is only accurate if your sample is at room temperature and if you follow directions as written.

The High Range product (HHWT-486676) uses no Molybdate catalyst; and therefore the reaction proceeds slowly. This allows for the detection range to be

Peracetic Acid Test Procedure

TR0

NOTE: Various oxidizing agents such as halogens, ferric ions, and cupric ions will produce high test
results. The detection of peracetic acid is very selective in the presence of peroxide and tests can
tolerate up to 35 times excess of Peroxide to Peracetic Acid ratio. If your Hydrogen Peroxide to
Peracetic Acid ratio is in excess of 35, it is recommended that Hydrogen Peroxide interference be
removed by adding a small amount of catalase enzyme to the test solution before testing.

Just before testing, rinse the sample CELL with the sample water several times to get a
representative sample. (Use deionized or distilled water for rinsing if you have a limited amount of
sample).

Store the meter and all test materials out of direct sunlight and away from chemical storage areas.

Minimize exposure of meter and test reagents to heat above 32°C (90°F).

Dry the outside of the meter when testing is complete or before storage of the meter.

a test is completed. Do not use solvents, such as acetone, to clean the cell. When the CELL becomes
stained or cloudy from repeated testing, or when the meter does not blank when you press the ZERO/ON

cleaning brush up-and-down and back-and-forth along the walls of the cell. Afterwards, rinse the cell and
the meter is ready for use again. Cleaning the cell regularly is especially recommended after you run a
test that is using turbidity or precipitation chemistry for analysis (Calcium Hardness and Cyanuric Acid).

1. Unscrew the O-ring sealed battery cover counter-clockwise. Use proper sized pliers if necessary.
Do not disturb the sealing O-ring. Batteries are not included.

2. Remove the used batteries and install 4 new AAA batteries following the diagram for
correct polarity (see diagram). We recommend high quality AAA alkaline batteries be used.

4. Replace the battery cover. Be sure to tighten the cover securely. This is necessary for meter to
be waterproof.

5. Dispose of the used batteries in accordance with your
local regulations.

NOTE: Because most of our products are test strips or use reagents that have little or no hazard in the quantity sold, MSDS sheets are not
supplied with the test.

To ensure optimal performance, store your eXact® kit in a cool, dry place away from excess heat (below
100°F / 38°C), moisture, and oxidizers such as Chlorine and Bromine.
