Encourage UV protection and be prepared when spending time outdoors with the ultimate UV detection kit. Kit contains one 250 pack of our popular and colorful UV beads and a pocket sized UV meter. This affordable UV meter detects both atmospheric UV-A and UV-B light ranging from 400 nm to 280 nm. It displays the current atmospheric UV index and the UV Irradiance. UV-A and UV-B are the UV rays that penetrate the atmosphere. A graphical meter alongside a UV color code chart makes it easy to determine the level of UV risk.
UV Beads change to a rainbow of colors when exposed to UV rays. Experiment with them in different UV conditions or make jewelry out of them which will always be a reminder of your exposure to harmful UV rays. Encourage inquiry by comparing the depth and speed of color change of the beads to the reading of the meter.
Small enough to easily bring along each day yet a powerful way to detect potentially unsafe conditions. Your kids will be excited to find out how extreme their UV risk is each day!
IMPORTANT: Product Usage Notes
1. The UV index and UV Irradiance is calculated by averaging the various UV-A and UV-B wavelengths according to the Erythemal Action Spectrum. UV flashlights, UV lamps and other lights that you may have in your classroom emit only one UV frequency; therefore, your UV meter will not give an accurate reading.
2. For consistent and accurate readings, the direction of the UV meter must be oriented so that the UV sensor points directly toward the sunlight.
3. If using glass in an experiment, please note that UV-B cannot go through glass, so the meter cannot get a reading through glass and will just register a zero.
UV Meter includes: Belt clip carrying case, convenient lanyard to wear around your neck, button cell battery CR2032, complete instructions.
