The QuantaDose® First edition 2020 Dual wavelength UV Test card consist of “two unique UV test strips” on “one reusable UV test card”. The QuantaDose® UVSAFE™ UV detector card is the world’s first narrow-band shortwave test card for detecting uv-c light combined with a separate UV intensity strip for an easy to use color gauge scale reactive to ultraviolet light between 200-400 nm.

The top UV test strip contains a special transparent analyte within the UVC test strip area that is engineered to mimic natures very own short wave UVC detector. Good ole ore Zn2SiO4, also referred to as the mineral composition of Willemite that reacts to UVC light by fluorescing bright green to identify effective shortwave UV-C germicidal light wavelengths.

Put the power of Willemite in your wallet! Don’t get stuck ‘Between a rock and a hard place’ by not testing your UVC lights with the world’s first edition QuantaDose™ UVC test card.

Willemite is a fluorescent metamorphic rock with a very unusual property of fluorescing only in the short wave UV. Using a short-wave UVC lamp (not black-light), the rock will glow green.

The QuantaDose® UV/UVC light indicator card exhibits these same properties in a new generation of photochromic UV intensity indicators that provide detection for man-made UVC and the suns natural UV that makes it to the surface of the earth.

The sun gives off many different wavelengths of light. Some of these wavelengths we can see with our eyes as “visible” light. However, did you know only about 2% of the wavelengths the Sun gives off are detectable by human eyes. Ultraviolet light (UV) is an example of light that cannot be seen by the human eye. (Other examples include radio waves, microwaves, infrared light, X rays, even gamma rays.)

The UV-B light that is present in sunlight exposure is good in moderation, and some types of UV exposure is just outright harmful, and the most dangerous UV wavelengths, namely those that fall into a spectrum named UV-C never make it to the surface of earth because these powerful yet short UV wavelengths are absorbed at the ozone layer of our atmosphere.

One way we can tell when ultraviolet light is present is with our skin, because ultraviolet light causes our skin to tan, burn, freckle and age.

Using photochromic colorimetric analysis is a basic, reliable, low cost, simple, in-house method of monitoring UV intensity along with verifying ultraviolet germicidal irradiation (UVGI). UVGI is an acronym for the use of ultraviolet (UV) energy (electromagnetic radiation with a wavelength shorter than that of visible light) to kill or inactivate viral, bacterial, and fungal species.
