Precautions for Using CC2602 Test Kit
Maintain coolant temperature to 10 to 54 °C (50 to 129.2
°F) while checking. 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 (89.6 °F) 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
concentration within the specified time range.
