Priceless peace of mind for reptile owners!
I keep bearded dragons. A couple of years back I had ordered new mercury vapor UV bulbs for my beardies but the regular brand I bought was out of stock, so I had to settle for what was supposedly a similarly reputable brand. I replaced 3 bulbs right away and within days noticed that one of my beardies was having trouble seeing and keeping his eyes closed most of the time. I worried but did not connect it to the bulb until a second beardie began having the same troubles, and then within hours, the third was also showing signs. I immediately removed all 3 bulbs as they were obviously the culprits. My two remaining beardies who did not get these bulbs had no symptoms whatsoever.All three affected beardies did recover, but the first to be blinded took the longest to get back to normal. I have since learned that this issue was almost certainly caused by dangerous UVC light which is the type used to kill bacteria and viruses, and is very harmful to living beings, and especially harmful to eyes. I’ve also learned that UVA and UVB bulbs created for reptiles are NOT well regulated or have much consistency even in the same brand. So having this meter to tell me exactly how much UV light is being put out by various bulbs, and at what distances from the bulbs eases my mind that I will never have my precious babies harmed by another poorly made bulb.Yeah I know this solar meter seems like a big expense, but it will save you and your beloved reptiles from what mine went through, and that is worth every penny.

I love this.. If you have reptiles you need this I know it’s expensive but get it.
If you have reptiles please get this ðð¼.It is easy to use! The preformence of the product is a god sent… It is definitely worth the price if you care for reptiles or starting out with a new collection of reptiles that need uvb.I kept putting off on buying this because it’s so expensive but one of my new reptiles I’ve had for 6 months (bearded dragon) was sick I didn’t know why and I kept telling myself ill buy this later ( because of the price) but it is sooo worth it. I had bought some uvb lights of someone on ebay (be careful) the UVB was not strong enough.( I’m not to sure why but this product is expensive everywhere I looked.)

Absolutely a great investment for any reptile owner
I am so so happy I decided to invest in one of these and canât recommend them enough for any reptile owner!!! This completely takes all the guesswork out of the amount of UVB your reptile is getting and may even save their life! Without a meter we donât actually have any way at all to make sure they are getting the amount of UV they need. Now I know exactly how much UV light he is getting, and I can check the bulbs to measure the output so I know when they need to be replaced instead of relying on just the manufacturer suggestion.When I first got this I tested it under my current T8 UVB bulb that wasnât more than a month old and it was barely putting out any UVB at all. Had I just followed the normal schedule for replacing them, my poor beardie who is a rescue that had MBD as a baby may have ended up suffering because of it.Needless to say I got a new light right away, but this time I got the Arcadia 12% T5 (which is considerably more powerful) to go with the larger enclosure I was also getting, and I used my new solarmeter to measure the UVI at different locations in his tank and tested out putting the light fixture in different positions in order to help me properly place it so he has a healthy gradient.I know itâs expensive, but this is one you should definitely consider! Itâs a one time investment that youâll find yourself using time and time again and coming to rely on to make sure your reptile is getting what they need. Also impressive to see that each unit is hand tested, calibrated, and comes with a certificate showing you when it was tested and certified.

Should be more affordable for all reptile owners.
I wish these were more affordably priced so more reptile owners could purchase them as you are truly just guessing without one of these. I was so far off of where I thought i was, that I am truly grateful I purchased this. It just worries me for everyone else gambling with their animals. I feel there is no reason this is this expensive except for the fact it âcan beâ because there are limited options out there. I ask the manufacturer or seller to consider lowering price (maybe not even a huge amount) so more people can afford this. It is a great product but using it can save pets lives

As far as I know it’s good, but hard to say as it worked once
I got this in, tested my UVB bulbs which I knew were old, replaced the bulbs and they were better, but not as great as I’d thought brand new bulbs would be, so wasn’t sure on accuracy of this. I did learn that you should let the lights run for a week or 2 to get a more accurate reading, so here it is 2 weeks later and the solarmeter won’t turn on at all. I’m hoping maybe it’s just because the “long life battery” inside is just dead already, but as I don’t have any 9 volts just laying around and won’t be able to get any for a couple days, unfortunately I can’t say with certainty that this product is worth the $250 I spent.If you’re able, it might be better to go with one of the higher price ones. I’ve heard great things about those. Heard good things about this one too so kinda upset that I got one use out of it. But then I guess I did make the mistake of ordering from crappy Amazon again

Works great, simple to use, item is exactly as pictured! A UVB reader is extremely important if you keep reptiles and they have UVB lighting! For me personally I own 14 different types of herps and quite a few of them have UVB lighting, so investing in this tool, will ensure that I save money in the long run! The reason being is I will know exactly how much or how little UVB the lights are producing, which will inturn ensure that I am not replacing UVB lights prematurely! (As if you know anything about keeping reptiles UVB lights are not cheap!)

Lange habe ich überlegt, weil es für mich auch nicht wenig Geld ist. Aber ich habe es mir dann doch gekauft. Zu meinem Erschrecken musste ich feststellen, dass die Lampen bei meinen Echsen, die das UV Licht besonders benötigen, so gut wie keine Wirkung mehr haben, wer weià wie lange schon nicht mehr.Jetzt konnte ich mal alles durchmessen und durfte/musste somit 2 neue Strahler kaufen.Dank diesem Gerät kann ich nun zeitig reagieren und entsorge keine Lampen mehr unnötig früh.280⬠sind für viele eine Menge Geld, aber im besten Fall hat man das Gerät auf ewig und wenn ich jetzt alle meine UV Lampen auf Verdacht getauscht hätte, wären es weit über 300⬠geworden.Jetzt sind es “nur” 80⬠für die beiden Strahler.Also hat sich das Messgerät bereits jetzt schon bezahlt gemacht.

Although it seems quite expensive this is one of the only UV meters I would recommend purchasing. I carry out a large amount of zoo and exotics veterinary work and require a reliable, high quality instrument for my work. I often find clients whoâs animals are not receiving the correct amount of UV supplementation despite the use of UV bulbs. A good quality UV meter is a must.

Endlich die UV Produktion der Lampen messen und über längere Zeit kontrollieren ⦠zuverlässig und einfach. Top Produkt – zwar nicht billig aber es gibt auf dem Markt nichts besseres um bei unserem Chamäleon die UV Einstrahlung zu überwachen.

A must have for reptile enthusiasts.. getting the right amount of UV for your reptile is most important.. this meter ensures that your lights are set up properly.. you can monitor their output and know when to change them without guessing. Great product!
