Precautions for Using CC2602 Test Kit
Maintain coolant temperature to 10 to 54°C while check-
ing. Otherwise, incorrect color change may result.
Compare the reagent color with the color specimen to
measure the concentration in daylight.
In case it is difficult to specify the color concentration
through the comparison of the reagent color with the
color specimen, adopt the lighter side concentration as a
safer value.
The reagents provided in the test kit are sensitive to light,
heat, and excessive moisture so that they should be
stored in a plastic container. Unless the test papers are
used, be sure to close the container cover correctly.
Avoid to expose the test kit to the direct ray of the sun
while storing and maintain the ambient temperature of
the storing place to 32°C or lower.

MAINTENANCE
The effective life time of the reagent is printed on
the upper section of the CC2602 container.
Do not use any reagents after the effective life
time expires.
If the reagent color has changed to light brown or
pink, avoid using such reagent.
If the color specimen was spoiled, wipe stain with
a cloth. Do not use any soap or solvent.
The reagent color continues to change from soon
after being dipped into coolant and stops after it is
dried up. Therefore, measure the coolant concen-
tration within the specified time range.
