READ THE ENTIRE INSTRUCTIONS BEFORE USING THE KIT
• Fill the plastic vessel with 25
mL of the sample, up to the
mark.
• Add 1 packet of HI 93722-0 reagent and, using the
spoon, mix gently to dissolve.
Note: In the case the line on the bottom disappears with
the liquid level under the 100 ppm mark , the
cyanuric acid concentration is higher than 100 ppm;
in the case the line disappears above the 10 ppm
mark, the cyanuric acid concentration is lower than
10 ppm.

Dear Customer,
Thank you for choosing a Hanna Product.
Please read the instructions carefully before using the
chemical test kit. It will provide you with the necessary
information for correct use of the kit.
Remove the chemical test kit from the packing material and
examine it carefully to make sure that no damage has
occurred during shipping. If there is any noticeable damage, notify your Dealer or the nearest Hanna office
immediately.
Each kit is supplied with:
HI 93722-0 Reagent, packets (100 pcs);
•
• 1 glass test tube (25 mL);
• 1 plastic vessel (50 mL);
1 plastic pipette (3 mL);
•
1 spoon.
•
Note: Any damaged or defective item must be returned in
its original packing materials.
Cyanuric Acid (CYS) is widely applied in swimming pools to
slow down the decomposition of chlorine. In outside pool
areas, this process is accelerated by the effect of ultraviolet
rays. With a correct dose, it can save up to 80% of normal
chlorine consumption in pools during peak sunny months.
Cyanuric acid is also used in chlorinated bleaches and
selective herbicides.
Note:
mg/L is equivalent to ppm (parts per million).
CHEMICAL REACTIONCHEMICAL REACTION
CHEMICAL REACTION
CHEMICAL REACTIONCHEMICAL REACTION
The reaction between cyanuric acid and the reagent causes
a white suspension in the sample. The turbidity is proportional to the concentration of cyanuric acid.

• Wait for 1 minute
to allow reaction
to occur.
• Keep the test tube on a white
surface and look from the top at
the black line visible on the
bottom of the tube. Use the
plastic pipette to fill the vial
drop by drop with the reacted
sample until the black line has
completely disappeared.
• Read the concentration in mg/L
(ppm) of Cyanuric Acid in correspondence of the level of the
liquid in the test tube.
