Color changes with UV radiation

Features:

• The irreversible color change : the color will not return to its original color, once changed.
• Four different sensitive levels available, depending upon applications
• No paper dust generated by labels
• Dia. 18 mm (0.7 in.) x 100 pcs/set
• Custom-made labels available upon request from 5 x 5 mm to 300 x 400 mm

Example:

Model	Radiation Quantity (mJ/cm2)
UV-S Very high sensitivity	0	5	15	50	100	250
UV-H High Sensitivity	0	50	250	500	1000	2000
UV-M Medium Sensitivity	0	250	500	1000	2000	3000
UV-L Low Sensitivity	0	1000	3000	6000	10000	15000

NB: The color tone and radiation quantities are based on the factory tests with a mercury lamp and a reference only. The color tone and radiation reading may differ depending upon the radiation conditions.

Applications:
>> For detecting UV hardening ink, paint, adhesives, resins
>> Maintenance of UV lamps (metal halid, mercury, sterilization, etc)
>> Monitoring UV radiation by sunlight (UV-L type)
>> Monitoring gamma rays and electron beam radiations

Cautions:

• Heat resistance : No color change was observed under no UV radiation environment at 100 degrees C for 10 minutes. Do not expose the label above 130 degrees C or the label will contract.
• The label will change its color with UV radiation by indoor fluorescent light.
• Do not apply the label directly to human skin.
