Instructions for use:

Place the test card flat on the table, and then use the test light to form a purple mark in the middle of the test card, indicating radiation. After the purple mark is gone, put the glasses above the test card to keep the blocked area of the test card away from radiation, without a bit of purple mark when the test light shining on.

The stronger the blue light, the deeper the irradiated area will change color.

Natural light contains blue light, which will cause discoloration of the test area and affect automatic recovery. Please test indoors.

The discolored area of the test card illuminated by the blue test light will automatically recover and turn white in 1-2 minutes.
