The dual wavelength multi-strip UVC test card measures UV intensity with a very specialized analyte for wide-band photochromic UV dosimetry combined with a narrow-band short-wave fluorescent indicator for testing optimal UVC germicidal wavelengths.

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

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

has created a specially formulated ink chemistry that is sensitive to only optimal germicidal UVC which will not fluoresce to visible light or UVA and UVB. This ensures only germicidal wavelengths between 250-270nm are shown in bright green.

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

Bottom Light Sensor Test Intensity of UV Exposure: When exposed to UVA, UVB & UVC wavelengths, the test card undergoes a gradual color change in seconds from clear to light purple, displaying the word "ULTRAVIOLET " at approximately 300 µW/cm² UVC and dark purple 3000 µW/cm² UVC that 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 most accurate intensity results. Test is completed in 15 secs, remove card from source!
Multi-analyte constituents provide fast chromatic analytical data for UV/UVC testing.
Photochromic dosimeter strip uses an analyte sensitive to wide-band UV between 200-400nm UVA/UVB/UVC
UV dosimeter color strip concentration is directly proportional to UV intensity (higher intensity equals darker color)
UV dosimeter color concentrations are also directly proportional to UVA UVB and UVC wavelength (shorter wavelengths equals lighter color) at max value.
UVC photo-luminescence detection technology displays temporary fluorescence between 250-270 nm when directly exposed to optimal germicidal UVC light waves.
