quantadose-1st-edition-uvc-test-cardDesigned and Engineered in the USA, QuantaDose uses photochromatic WPV (Word Power Visibility) technology to provide reliable UVC intensity readings in 15 seconds with instant notification of optimal UVC germicidal wavelengths. The QuantaDose UVC intensity test card relies on calibrated word legibility starting > 300 µW/cm² when the word ” UltraVIOLET” first becomes legible during exposure to optimal UVC germicidal wavelengths.


QuantaDose UVC test cards are a basic, reliable, low cost, simple, in-house, and right out of your pocket method of monitoring UVC intensity along with verifying that the optimal UVC light wavelengths are being used in your disinfection process without spending hundreds of dollars on fragile UV and UVC light meters.

QuantaDose provides you with real-time results super fast.  When exposed to optimal UVC germicidal wavelengths, the QuantaDose UVC test card undergoes an instant color change to a green where fluorescence is directly related to the energy value received. Fluorescence stops when excited electrons release all photos within nanoseconds after exposure.

QuantaDose has created a specially formulated ink sensitive to only optimal UVC, which will not fluoresce visible light or UVA and UVB. This ensures only wavelengths between 250-275nm are shown in glow green.  QuantaDose gives you verification/validation purposes to avoid an increasing number of defective UVC light products on the market today.

  • Verify the wavelength of light being emitted
  • Validate the amount of light being emitted
  • Confirm the amount of light reaching a surface

These easy-to-use, credit card-sized UVC Indicators will increase the UVC light disinfection processes’ efficiency by helping you visualize what is most effective. The amount of inactivation is directly proportional to the UVC dose, which is received, and this, in turn, is the result of its intensity and duration of exposure.  The farther away from the light source, the less UVC will reach the target, so only a quarter of the UVC remains when the distance doubles.

STEP 1) Top Light Sensor Test Wavelength of UV Exposure: When exposed to optimal UVC germicidal wavelengths, the QuantaDose UVC test card undergoes an instant color change to the green fluorescence is directly related to energy values of UV wavelength received. Fluorescence stops when excited electrons release all photos within nanoseconds after exposure.


STEP 2) Bottom Light Sensor Test Intensity of UV Exposure: When exposed to confirmed UVC wavelengths, the QuantaDose test card first displays the word “UltraVIOLET ” at approximately 300 µW/cm² a gradual color change is directly related to the energy value received. Temporary photochromic dosimeter color is used to check intensity after exposure and should be checked immediately after exposure for the most accurate intensity results. The test is completed in 15 secs; remove the card from the source!

REQUIRED FDA NOTICE: Photochromic material used for UVC intensity testing should never be used to decide when to apply sunscreen to prevent a medical condition (sunburn) that requires classification as a medical device.  Please consult your doctor for sunscreen advice if you have questions about the sun’s UV intensity measured on your QuantaDose card.  QuantaDose should never be used as a medical device to assist you in when to apply sunscreen.

QuantaDose photochromic material used has hundreds of off label uses, from detecting UV from the sun, UV science projects, detect counterfeit UV rated sunglasses, easily detect fake UV-C LEDs and badly degraded UVC bulbs.  The QuantaDose UVC indicator is useful for reptile owners that purchase UV lights for their pets to ensure a harmful light isn’t being used on them while still testing the bulb intensity levels.  You can even test what you think might be shaded from the sun’s UV rays by simply pulling out the QuantaDose card.  Did you pay to have your windows in your car and home to be shielded from the sun’s UV?  QuantaDose makes it easy to see if you got what you paid for!

However, please don’t lose sight of the most important reason the QuantaDose WAS created — to be a consumer’s front-line defense tool to ensure they use real UVC over the fake UVC products flooding online marketplaces today!

QuantaDose is a versatile UVC test card with a wide-band photochromic test area that provides lots of useful information about these potentially harmful invisible rays of ultraviolet light.  The QuantaDose UVC test card has only one intended use; this is a two-part UVC test to verify UVC wavelength and easily visualize a minimum UVC power intensity in seconds.
