Crystal CO2 Indicator Large – SMALL

The UV-B Quick Test is a quick and easy tool to determine whether the UV product still emits enough rays. The card reads the intensity of UV-B rays, UV-B fluorescent lamps or UV-B compact lamps using a new, non-toxic and eco-friendly high-tech detection material agent on the card. The colour change on the card indicates whether UV-B rays are still being emitted. The colour of the surface on the card changes from white to purple depending on the intensity of the UV-B rays. The card can be reused up to 500 times. But this card is also a great tool outdoors to test whether the UV-B level is too high. If the colour of the card changes to purple, it’s best to stay in the shade.

Use:

This reusable card can detect UV-B rays within 10 seconds. Hold the card under the UV lamp, directly in the spotlight (approx. 5 cm from lamp) to test if the lamp still emits UV-B rays. If the card shows a “purple surface” under the UV lamp, the lamp

is still emitting UV-B rays.

Caution: Replace UV lamps at least annually or sooner. This card only serves as a guide.

If the card does not change colours, replace the UV-B lamp immediately.
