Sunlight UV Index Meter with UV Dose Reminder. Beep Alert When Selected UV Dose Limit is Reached. No Use Times Limitation

Editor's bottom line:

“This uv light measure is the best one we tested. In terms of quality, brand and price, we couldn't ask for more.”

Main Highlights

Accurately measure sunlight UV index: 12 Low, 35 Moderate, 67 High, 810 Very High, 11+ Extreme. Reusable no limit on usage.
High instant UVI does not mean skin is harmed immediately. UV exposure builds over time, and skin risk depends on both UV intensity and exposure time. AH-Sunuvi is designed to give a beep alert when the selected UV dose limit is reached.
Choose Your Reminder Level Select Low, Medium, or High UV dose reminder level based on your preferred caution level. When the selected UV dose limit is reached, AH-Sunuvi gives a beep alert while the screen continues to show the current UVI.
Sunscreen protects. AH-Sunuvi reminds. Sweat, water, towel drying, and time outdoors can reduce sunscreen protection. AH-Sunuvi gives a beep alert when the selected UV dose limit is reached.

EIDEAL

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

Main Highlights

3-in-1 REUSABLE CARD - The EIDEAL UV & UVC Test Card is double-sided. On the one side, you have two tests: UV light and UVC light, which indicate whether a bulb or light is indeed irradiating the type of UV light that it claims. On the other side, you can test any UV or UVC bulb's remaining intensity. Remember UV lights have a life span of about 9000 hours. We recommend storing the card in the packaging sleeve to protect the sensitive test area.
SIMPLE TO USE - These cards have been designed to be simple to use and easy to understand. No confusing instructions and the card gives a clear indication of the test results. Please note that the intensity scale gives an approximate indication of the intensity remaining in a bulb. Should you require a more accurate reading, please use a Radiometer/ Optometer.
HOW TO READ RESULTS: The UV & UVC test has to be observed directly under the light that you are testing. The letters will disappear immediately when not irradiated by the light. The UV Intensity test side can be used in a closed box or directly under the light. This test gives an indication of the UV or UVC remaining in the bulb depending on the time you leave the card exposed to the light. To calculate UV Dose: UV Intensity (W/cm² - the reading which the card gives you) x Exposure Time (seconds).
DIFFERENT USES/ TESTS - So you have bought this UVC sanitizing wand, but is it emitting the correct wavelength to kill all harmful bacteria as promised? The UV protection film that is installed on your car windows, does it block all UV as claimed? And those UV blocking glasses, are they protecting your eyes? Find out!
DEVELOPED WITH THE CUSTOMER IN MIND - We wanted to create a simple to use card with added value. A lot of thought and investigation went into the planning of this card so that it would be easy to understand and simple to use.

QuantaDose

6-in-1 QUANTADOSE® Multi-Wavelength Bi-Luminescent UVA/UVB/UVC/Far-UVC Light Reusable Professional UV Test Card

Main Highlights

There is no other UV test card like this with all new capabilities using tri-color dispersion in the worlds only reusable bi-luminescent (Two Color) instant wavelength indicator that distinguishes between artificial sources of longwave UVA and shortwave UVC light with a residual third color shade of purple indicating UV intensity in 15 seconds
WHILE UNDER UV LIGHT: The 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
WHILE UNDER UV LIGHT: 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
AFTER UV EXPOSURE: Photochromic dosimeter strip uses a wide-band UV analyte sensitive to artificial or natural sources of light between 200-400nm UVA/UVB/UVC, which before exposure is clear, after exposure displays shades of purple. Perfect for testing the intensity of anything UV including UVB reptile lights, with instant notification when unsafe wavelengths are present
AFTER UV EXPOSURE: 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 test card has UVC/FAR-UVC light beam detector useful when installing Far-UV lighting in occupied spaces. This QuantaDose test provides the largest shortwave luminescent surface area available on the market that still fits in your wallet. Exactly what professional UVGI installers need to detect UVC/Far-UVC beam angles!
SCHOOL/TEACHING Experiments on Ultraviolet Light and Fluorescence are easily performed in the classroom to explore different wavelengths of the UV light spectrum.
MANY USES - Test UV blocking claims for items like sunglass, window tint or test UV light sources such as sterilizing LEDs and UVC bulbs, nail curing lamps, UV print equipment. The list goes on and on! When not in use keep stored in the supplied UV resistant zip lock sleeve or store it in a dark, dry place.. Limit UV light exposure times to 15 seconds for > 500 test.

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.
