The Hobby UV-B Quick Test is a quick and easy tool for determining the intensity of UV-B rays emitted by fluorescent or compact UV-B lamps. It uses non-toxic and environmentally friendly detection material.

The card reads the intensity of the rays, with the color change indicating whether UV-B rays are still being emitted. The card changes color from white to purple depending on the intensity.

• Reusable up to 500 times.
• Can also be used outdoors to check UV-B levels.
• The color change to purple indicates a high level of UV-B.

Usage: The card detects UV-B rays within 10 seconds when placed about 5 cm from the UV lamp. The card is considered valid if it displays a purple surface under the lamp.

Attention: Replace UV lamps at least annually. If the card does not change color, replace the UV-B lamp immediately!
