$28.95
This UV meter detects both atmospheric UV-A and UV-B light (ranging from 400 nm to 280 nm) and displays the current atmospheric UV index. Students then can relate this numerical index to our color changing UV beads or our light sensitive Print Papers: how dark the color or how quick the change. Note: the meter is not sensitive to the rather narrow frequency of UV light emitted from artificial sources such as a UV flashlight or UV lamp. Meter requires a 3 volt CR2032 button battery (included).
