UV FASTCHECK STRIPS are simple, reliable, and easy to use indicators of accumulated UV light dosage. They are the first product that can be used to determine levels of UV dose with a simple, visual inspection due to the 5 separate color changing zones. Each of the 5 zones begin to change color after a specific amount of UV dose has been received. First the "1" zone begins turning from yellow to blue. Then each subsequent color zone starts to change colors when its specific chemistry has received the proper amount of UV to activate its color change.
The versatility of this unique UV measurement tool allows users to measure a significant range of UV doses. UV FASTCHECK STRIPS measure UVA/B doses from 0mJ/cm to greater than 5,000mJ(5J)/cm. As well, due to their paper-thin profile and thermal stability, they can be used in all applications where a radiometer is not possible, including: Web printing, Sheet Fed printing, Exposure Verification of exposed products, 3-D curing, and personal UV exposure level testing.
The UV FASTCHECK STRIPS' clearly identifiable color change enables users to visually differentiate the dose differences. To measure the dose even more precisely, use a spectrophotometer to record color change by the UV FASTCHECK STRIPS. NOTE: For best results, observe color change immediately after exposure to UV light as label may change/fade over time.
As well, a comparative dose chart for the UV FASTCHECK STRIPS is included in each package. With this chart, each tested UV FASTCHECK STRIP can be visually correlated to the millijoule range of UV energy that each color pattern represents.

All five squares are yellow, first square will change color immediately in UV light

The first square is the deepest green.

The rest are increasing degrees of yellowish green.

The first square is now a dark green.

The other squares are progressively more green.

Now the 1st square is blue and the next 2 squares are a blue-green.

The 4th and 5th squares are a deeper green.
