Model 5.7 Sensitive Total UV Meter - Measures 280-400nm with range from 0-1999 µW/cm² Total UV

Does exactly what it is supposed to do. Where I live (7500' above sea level,) the UV is sometimes offscale (Yikes!) but with it, I have been able to precisely quantify how much UVA and UVB various plastic, glass and sunscreen materials work. Big surprise - some sunscreens are way less effective than advertised... I anticipate using this to protect my family from UV exposure, and to design an effective greenhouse, among other things... Very useful tool with very reproducible results. At some point, I may adapt a UVB filter to enable distinction between UVA and UVB contribution to measurement, but it is a great tool. It's also incredibly easy to use.

I’m not an expert on electronics, nor am I reptile keeper. I got it to check UV intensity in a hanger to make sure that the solar windows are adequately protecting fabric on an airplane. Outside measurements were in 1600 range when indoors it went to 70‘s, and under a tarp or a shield drop to 3 on a heavier cover and nine on an alternate. This is gibberish except for the fact that it test the theory that this is a very sensitive device. Probably could’ve gotten the standard one but this one meets the criteria for exceptional UV protection when you’re trying to make sure things don’t fade in your home because of UV exposure. Cannot address the reptile function that people talk about. That’s another topic.

Este medidor lo usamos para mejorar la calidad de vida de nuestro nieto, diagnosticado con una enfermedad minoritaria llamada Xeroderma Pigmentosum.Los rayos ultravioleta, infrarrojos y cualquier fuente de luz, excepto los LED, provocan a los afectados graves quemaduras en la piel, que pueden convertirse en cancer de piel, ademas de otras afectaciones.El uso del medidor ayuda a determinar cuando puede quitarse la ptroteccion total y cuando no.

Perfect for measuring UVA/B penetration through windows or shades, with or without protective film

Exactly as described.
