QuantaDose™ is the only UV intensity card meter that distinguishes between the sun’s natural UVA/UVB radiation and human-made sources of germicidal UVC wavelengths simultaneously.   More in-depth information on how to use a QuantaDose™ UVC Test Card to check if your UVC LED lights are real germicidal LEDs.  How to tell if UVC is working?

Fake UVC Lights & Test Strips?

Quantifying QuantaDose™UVC Rapid Test with American Ultraviolet UVC Dosimeters by Intellego Technologies and General Tools UV512C UVC light meter.

The below video shows UVGI wavelength and the minimum of 300 µW/cm² confirmed by QuantaDose™ intensity gauge for rapid disinfection. The 35-watt bulb peaked at 350 µW/cm² at full operating temperature. Notice QuantaDose color when exposure reaches 300 µW/cm² as the bulb warms up to reach the minimum intensity for a color reaction to occur. At this intensity, a 100 mJ/cm² accumulative exposure is reached in 5 minutes as confirmed with American Ultraviolet’s UVC Dosimeters by Intellego Technologies, and the real-time readings in µW/cm² are provided with a General Tools UV512C UVC light meter.

Increase the efficiency of UVC light disinfection and UV safety

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

When exposed to UVC germicidal wavelengths between 250-275nm, the QuantaDose™ test card undergoes a rapid color change to the green, where fluorescence is directly related to the energy value received.

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

The dual feature of the QuantaDose UV and UV-C test card is based on the molecular change principle when excited with light’s high energy wavelengths.

When a photochromic molecule’s energy absorbs energy from sunlight and ultraviolet light, the structure of the molecule changes, and photons are reflected at a shorter wavelength, resulting change in the reflected light’s wavelength, which ultimately changes the color of the substance.

When the energy from sunlight or ultraviolet UVC light is released, the molecule returns to its original structure, and the color returns to its original color. This temporary change in reflected light is what makes QuantaDose™ photochromic UVC measurement cards such as a consumer-friendly assessment tool by allowing them to be used over and over again.
