UV-B Quick Test 2 Stck. SB

The quick UV-B test is a fast and easy tool to determine if the UV product still emits a sufficient amount of rays. The card reads the intensity of UV-B rays, UV-B fluorescent lamps, or compact UV-B lamps using a high-tech, non-toxic, and eco-friendly reagent. A color change on the card indicates whether UV-B rays are still being emitted. The surface color 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. However, this card is also a great outdoor tool to test if the UV level is too high. If the card changes color to purple, it is best to stay in the shade.
Usage:
This reusable card can detect UV-B rays within 10 seconds. Hold the card under the UV lamp, directly in the light spot (about 5 cm from the lamp) to test if the lamp still emits UV-B rays. If the card shows a "purple surface" under the UV lamp, the lamp
Still emits UV-B rays.
Warning: Replace UV lamps at least once a year or sooner. This card is just a guide.
If the card does not change color, replace the UV-B lamp immediately.
