QuantaDose™ Dual wavelength photochromic intensity indicators are a basic, reliable, low cost, simple, in-house method of monitoring UV intensity along with verifying UVC radiation.

  • Verify the wavelength of light being emitted
  • Validate the amount of light being emitted
  • Confirm the amount of light reaching a surface
  • Detect between 320-400nm UVA/UVB on one scale, and 254-280nm UVC on another from the same reusable UV test card

With an increasing number of fake and defective germicidal UVC products on the market QuantaDose™ provides you with real-time results for super fast verification/validation purposes.

This easy-to-use, credit card sized 85.60 mm by 53.98 mm (3 3⁄8 in × 2 1⁄8 in) UV/UVC test card is an economical way to visualize when the UV disinfection process has truly delivered a powerful level of UVC energy to the target for sterilization.

Increase the efficiency of UVC light disinfection and UV safety

When exposed to UVA and UVB wavelengths, the QuantaDose™ test card undergoes a gradual color change from light purple to dark purple that is directly related to the energy value received.

When exposed to UVC germicidal wavelengths, the QuantaDose™ test card undergoes a rapid color change to green where fluorescence is directly related to the energy value received.

Multiple Usage Scenarios

QuantaDose™ the most versatile UV/UVC test card on the market today. Gauge when the sun’s natural UVA/UVB radiation warrants protection and test that your germicidal UVC lighting performs as advertised.

Simultaneous UV Detection

QuantaDose™ is the only UV intensity card meter that distinguishes between the sun’s natural UVA/UVB radiation and man-made sources of germicidal UVC wavelengths simultaneously.

UVA/UVB Detection

UVA comprises of almost 95% of the light that reaches our skin, UVB makes up the rest. The FDA and World Health Organization have all declared UV radiation a known carcinogen. Natural and artificial sources.

UV-C Detection

Specially formulated ink chemistry that is sensitive to only UVC will not fluores to visible light or UVA and UVB. This ensures only germicidal wavelengths between 254-280nm are being shown in green.

Disinfect Visually

QuantaDose™ eyes-on innovation

The amount of pathogenic inactivation is directly proportional to the UVC dose and this in turn is the result of UVC intensity and duration of UVC exposure. The farther away the light source, the less UVC will reach the target, so UVC intensity is reduced to a quarter when the distance doubles. Get the strength by quantifying UV power with QuantaDose™!

How do you test for fake germicidal UVC LEDs?



QuantaDose™ UV/UVC Photochromic Test Card

Also referred to as UVC Test Strips, UVC Indicator Strip, UV Germicidal Test Strips, UVC Reactive Strips, UV-C Test Card, UVC Indicator Card, Dosimeter Strips, UVC Dosimeter Cards, UVC Light Test Strips, UVC Detector, UVC Test Kit, UVC Visualizer Strips, UVC UVC Intensity Labels, UVC Visualizer Strips and most accurately called a Photochromic UVC Measurement Test Cards.

What makes QuantaDose™ photochromic UVC measurement cards so consumer friendly is when the energy from sunlight or ultraviolet light is released, the molecules in the photochromic substances return to their low energy state and the color returns to its original color allowing it to be used over and over again.

The UV/UVC test card is based on the principle of molecular change. When the energy of a photochromic molecule absorbs energy from sunlight and ultraviolet light, the structure of the molecule changes, resulting in a change in the reflected light wavelength, which ultimately changes the color of the substance providing a indicator for UV and short-wave UVC exposure.

The germicidal effects of UVC irradiation results in cellular damage by photohydration, photosplitting, photodimerization, and photocrosslinking, thereby inhibiting cellular replication. Today’s easy to use compact UVC technology allows us to fight the virus outside our bodies!

The technology QuantaDose™ uses consist of a photo-chromatic ink that changes color when it is stimulated by certain UVC radiation (Top UV Indicator Strip: 250- 275 nano-meters. Bottom UV Indicator Strip: 200- 400 nanometers ).

Germicidal UVC light is an effective tool for eliminating pathogens on surfaces and in the air, but how do you know that the UVC dose is effective? How do you know if you purchased an effective or even real UVC disinfectant light from Amazon, ebay or any-other online retailer that allows 3rd party resellers willing to take advantage of the current pandemic?
