Solarmeter Model 6.5 UV Index Meter, Handheld Digital Radiometer for Measuring Ultraviolet Light, Measures 280-400 nm with Range from 0-199.9 UV Index, Made in USA

Works great! Love being able to check my UVB

Most reviewers bought this meter for a lizard. Guess what... I wanted it to help better protect MYSELF and my family from UV exposure. There's so much misleading info online about how much UV gets through windows, clothes, clouds, etc. Although this sensor is pricey, it was worth it because I was able to get an accurate UV reading in all kinds of conditions and better understand when extra sun protection is really needed. For example, I found that my existing car and house windows do an excellent job of filtering UV (readings of 0.0-0.1 if the outdoor UV index is 7.0). This means I don't need to worry about applying sunscreen (which irritates my skin) every single day to my arms if I'm just going to be driving or sitting near a window. Your windows may differ... according to the internet, many windows don't do a good job of filtering UVA. I also learned that my existing clothes and sun hats block UV well (some internet sources claim that they don't unless you buy special "UPF" products). I confirmed that one warning is true, some UV gets through clouds, and some gets to me on a sunny day even if I'm sitting in the shadow of my house. I was able to verify that all of my prescription sunglasses as well as the cheaper drugstore sunglasses filtered UV as well as they claimed! However, a pair of "toy shades" that came with a costume let a substantial amount of UV through and should not be used as sunglasses! Overall, this meter was a great purchase for peace of mind, for understanding when UV exposure is significant and needs to be mitigated, and avoiding paranoia when it is not.

This UV meter works great! It gives quick, clear readings and has been really helpful for monitoring sun exposure during outdoor activities. It’s small, portable, and easy to read—even in bright sunlight. Definitely a handy tool for anyone concerned about UV safety.

Bought a few years ago-its saved me more than the product cost in T5HO UVB bulbs. Apparently they last WAY longer than the reccommended replacement period. We had one that went for over 2 years until the bulb burnt out.

Couldn't get this to register anything other than 0.00. Total waste.

Great product, easy to use, good price point, a necessity for southern dwellers, the Sun is stronger than you may think. I tested it against reliable reporting, it spot on. Scary to see how damaging the sun can be at midday. The Ozone layer moves, it is not always there, just ask the Australians, they know first hand.

I have a weather station in my yard with a UV meter. The readings on the weather station match the Solarmeter. I checked multiple times during the day. The Solarmeter has a calibration certificate, so that makes me confident my weather station is accurate. I used this to check sunglasses and clothing that claim to block UV actually work, and they do. It only displays the reading while you hold down the button. When you release the button, the reading is gone. I wish it had a hold function for times when it's not convenient to look at the display while taking a measurement. For instance, I'd like to take a sun measurement, then cover the meter with a shirt, and see if it goes to zero. But I have to keep the button held down, so when I remove the shirt I'm measuring direct sunlight again. It's easy enough to get around that, but a hold function would be nice. It still rates 5 stars.

Like some other purchasers, I don't own lizards - I bought this tool to measure UV radiation in various locations in different circumstances. With my Irish complexion, I've had many skin cancers and needed a simple device that would give quick, accurate readings. This is what I've found out so far: my car, both front windshield and side windows, provides excellent UV protection; at work in my windowed office, again, excellent protection. I've noticed that even in the shade of a tree or building shadow, there are still UV rays getting through (though greatly reduced versus direct sunlight); also, cloud cover cuts the UV rays quite a bit (although not as much as shade does). If you're curious to know the UV index in real time where you are, then buy this nifty product.

Complete waste of money giving the same readings indoors as outdoors ,constantly reading 01.9..is this 1.9 or 0.19 ? no instructions very very poor for the money...avoid

Very easy to use and arrived in immaculate condition. My only concern was the calibration of it hadn’t been kept up to date. The calibration date expired in May 2018. I wasn’t aware that this had to be done on an annual basis before.
