It confirms UVGI intensity above 300 microwatts at 254nm and features a dual-sided design for wavelength and beam angle detection. Perfect for professionals requiring accurate UV verification in healthcare, beauty, education, and industrial settings. ## Description 6-in-1 REUSABLE CARD – Quanta X Technology, located in the USA, has created specially formulated fluorescent photochromic wavelength indicators for PHz electromagnetic waves in the ultraviolet light spectrum that capture UV light in a photochromic quantum confinement effect and molecular fluorescence effect simultaneously, creating the QuantaDose frequency-sensitive UV shortwave/longwave sensor card indicator for easy UVA/UVB/UVC wavelength conformation and intensity test. The QuantaDose Multi-Wavelength Bi-Luminescent UVA/UVB/UVC/Far-UV Test Card has functionality on both sides. On the one side, you have five tests: 1st a UVC indicator Test, 2nd a Wideband UV Intensity Test, 3rd a Shortwave Test, and 4th a Longwave UV Test, which is designed to indicate whether a UV bulb or UV light is indeed irradiating the type of UV light as claimed, most important is the 5th test that confirms >300 microwatts at 254nm UVC when the letters UV remain visible in the inner circle after the card is removed from a UVC light source. On the other side, in the 6th test, you can test any UVC or Far UVC bulb’s beam angle with a large surface area of the test card covered in a luminescent shortwave analyte sensitive only to UVGI wavelengths. We wanted to create a self-powered simple-to-use test card that was a multi-tool for UV light detection. Over two years of R&D went into this card so that it would do what no other test card ever designed could do. Reusability when detecting UV spectrum between Longwave UV, Shortwave UV, UVGI UVC, UVC Intensity conformation, and UV intensity scale all in one easy-to-use test card. Review: Works as advertised - It does work as advertised. I am not sure how accurate it is, however, the level indicated seems to match what is expected in the area and based on the time of the day. The instructions can be clearer. Review: Totally useless product. - This card does not do anything at all even in direct UV light. I also purchased a 395nm UV flashlight and even when it is shined directly on this this card, it does nothing at all. I can't get it to fluoresce or change color under any circumstance, including natural sunlight.

No inquiries will be answered." ## Features - The world’s only reusable bi-luminescent (Two Color) wavelength indicator that distinguishes between artificial sources of longwave UVA and shortwave UVC light - Longwave analyte is sensitive to artificial sources of 300-395nm UVA/UVB light, which before exposure is clear, while under a Longwave UV source will glow in the range of red to red-pink in color. Perfect for testing 365nm/395nm UV flashlights and professional nail gel UV lights - The shortwave analyte is sensitive to artificial sources of 220-275nm UVC light, which before exposure is clear, while under a Shortwave UVC source will glow in the range of Green to Yellow-lime in color. Instantly indicates when UVGI wavelengths are present - Photochromic dosimeter strip uses a wide-band UV analyte sensitive to artificial or natural sources of light between 200-400nm UVA/UVB/UVC. Perfect for testing UVB reptile lights, with instant notification when unsafe wavelengths are present - UVGI Intensity Test -- Center circle will display the letters UV for a brief amount of time (3-15 seconds) which confirms power is above 300 microwatts when exposed to 254nm UVC light.Back of card has UVC/FAR-UVC light beam detector useful when installing Far-UV lighting in occupied spaces.SCHOOL/TEACHING – Experiments on Ultraviolet Light and Fluorescence are easily performed in the classroom to explore different wavelengths of the UV light spectrum. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BK1772JY | | ASIN | B0BK1772JY | | Batteries Included? | No | | Batteries Required? | No | | Customer Reviews | 4.3 4.3 out of 5 stars (273) | | Customer reviews | 4.3 4.3 out of 5 stars (273) | | Date First Available | 9 August 2024 | | Date First Available | 9 August 2024 | | Included components | UV Light Test Card | | Item Package Quantity | 1 | | Item Weight | 32 g | | Item model number | QXT0032023QD | | Item model number | QXT0032023QD | | Manufacturer | Quanta X Technology | | Manufacturer | Quanta X Technology | | Material | Gel | | Part number | QXT0032023QD | | Product Dimensions | 8.56 x 0.15 x 5.4 cm; 32 g | | Product Dimensions | 8.56 x 0.15 x 5.4 cm; 32 g | | Special Features | 6-in-1 REUSABLE UV TEST CARD | ## Images ![Multi-Wavelength Bi-Luminescent UVA/UVB/UVC/Far-UVC Light Test Card - Image 1](https://m.media-amazon.com/images/I/61Sc-N3C0wL.jpg) ![Multi-Wavelength Bi-Luminescent UVA/UVB/UVC/Far-UVC Light Test Card - Image 2](https://m.media-amazon.com/images/I/61WsrR9vWyL.jpg) ![Multi-Wavelength Bi-Luminescent UVA/UVB/UVC/Far-UVC Light Test Card - Image 3](https://m.media-amazon.com/images/I/71jETG9l6iL.jpg) ![Multi-Wavelength Bi-Luminescent UVA/UVB/UVC/Far-UVC Light Test Card - Image 4](https://m.media-amazon.com/images/I/61vjHv7QxjL.jpg) ![Multi-Wavelength Bi-Luminescent UVA/UVB/UVC/Far-UVC Light Test Card - Image 5](https://m.media-amazon.com/images/I/81c-QUFOAvL.jpg) ## Questions & Answers **Q: how do you use this for uvc if you can't look at the light? is the only option to set up a camera?** A: I generally use uvc glasses and long-sleeved shirt to be around uvc- and only for very short periods of time at worst. However, best practice is to never be around the light while on. The exposure card can be read right after turning off the uvc light, but you need to make haste or it will recover as that particular card is reusable. These work- and can tell you if your light is indeed uvc, or uva/b. I have confirmed that in my lab. As with all UV lights, use safety protocols: never expose your eyes to any UV light, and never expose skin to short-wave UV light such as UVA, B, or C, nor breath air that is changed into ozone (O3) generated by wide freaquency UVC or low frequency UVC as that is toxic, and deadly to air-exchanging organisms. Always read the manufacturer's safety instructions before using. **Q: Can this distinguish long-spectrum UVB rays from short-spectrum UVB rays? Or are the long/short-wave labels just a generalization between UVA+B/C?** A: It takes some understanding of the test card surfaces to distinguish between wavelengths of UVB but if you have a long and short-wave UVB light to calibrate what you are looking for you will see a difference as you get close enough to UVC ( shortwave UVB 310nm) the letter starts to become slightly visible without with a very faint glow of pink in the main test area. **Q: It sounds like this detects both 254nm and 222nm, but cannot distinguish between them. Is that correct?** A: There will be very little difference between 254nm and 222nm for the green color. As far as the wide-band purple. There will be a very noticeable difference in how much energy it takes to make the letters UV remain visible in the center circle after exposure. For 254nm that's approximately 300 microwatts and for 222nm it's approximately 3000 microwatts. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as advertised *by A***G on 5 April 2026* It does work as advertised.
