EIDEAL™ | UV & UVC Test Card & UV Intensity Test Card | 3-in-1 UV Test Card | UVA & UVC Light Identifying Card | UV Bulb & LED Intensity Reading Card | UV Dosage Indicator Card | UVB Tester

This is a super simple UV tester - it gives plenty of info, including intensity. It is inexpensive and easy to use.

Works very, very well! I have very photo sensitive skin and I have to protect my skin at all times, even indoors(due to windows/skylights). This little card gives me instant information regarding the sun's UVA rays. This is the second time I have purchased this card. My first one lasted about 3 years, and I was using it all the time. My husband used my card, to check on his greenhouse lights all the time. It had been a wonderful little tool that fits right in your pocket!! Thank you so much!

This UV, UVC detection card works great. I was surprised that even indirect sunlight gives a slight UV reading. In direct sunlight, the UV indication is immediate and strong. I bought this mainly to detect UV from lights in the house because my wife just had cataract surgery and has the premium lenses installed that will be adjusted in the office with UV light. She has to wear UV blockers until the final UV adjustment is made in the office. The new lenses in her eyes are amazing. Within days she was reading the 20/30 line and can read small print. You only need 20/40 to pass the driving test in WA state. The 20/30 should improve with subsequent UV treatments.

Pros: * Very sensitive to UVA/UVB, more so than other cards I've tried * Reusable Cons: The hue of the scale is completely different from that of the test area, so it is impossible to actually use the scale. See the image: what intensity is it? Who knows? This card is not usable for measuring intensity. I don't mean it is inaccurate: it is completely unusable in this regard.

This is great. Back when Covid happened I had ordered UV lamp to sterilize items. I was skeptical whether it was actually the right wavelength. Now I have confirmed it is truly UVC. Whereas, UV flashlight that I have is not UVC. And so the flashlight is relatively safe for the eyes. This just confirms that the card works. Now I will be curious to use this in the daytime to see how much exposure I'm getting so I can avoid getting sunburns and skin cancer. One little point of clarification is that the side that says UV means A or B. It does not light up from my UVC emitter.

Basic readings, more for detection than measuring intensity but will do the trick. I got this for my UV light filtration system for my furnace. The bulbs run almost $100/ea so I'd rather check rough intensity to determine replacement than just replacing them on a 12 month schedule. Also found this card to come in handy for measuring a UV flashlight and my various sunglasses as to which are better filtering and which less.

It works.

Buenísimo lo llevo conmigo siempre para probar donde me debo proteger mas.lo pruebo en todos los lugares carro ventana parque puerta muy muy util

Review for: 'EIDEAL™ | UV & UVC Test Card & UV Intensity Test Card | 3-in-1 UV Test Card' This test card is very easy to use, reacts quicky to a UV light source, and gives a clear easy to understand result. When the UV light is turned off, the card quicky returns to its normal state/colour. Great for testing sunglasses.

Si detecta muy bien la radiación UV Un poco cara para lo que es

Used this to check uv sensitivity of face masks. Seems to be effective with checking UVA and and UVB. First was with dark tinted mask that blocks UVA and UVB, second was with mask that mentioned uvA and uvB protection but did NOT and third picture was in direct sunlight. See attached for photos.

Buena calidad. Es lo que dice.

Excellente achat.
