Check that brand new bulbs are up to par with manufacturing standards and track their aging to replace them as soon as they're not working the way they should. The Solar Meter Model 5. 7 Sensitive Total UV Meter measures the UVA+B region from 280-400 nm. Applications include monitoring PUVA therapy lamp intensity and aging, measuring outdoor UV, testing acrylic shield transmission, eyewear UV block comparison, and testing window film / tint transmission. The simple, one-hand operation of this device makes it easy to monitor UV light intensity levels to decide when it's best to do outdoor activities.

## Questions & Answers

**Q: could this meter be used to measure UV emitted by artificial light sources?**
A: Yes, but it measures only the UVB index. For example UVB index of terraristic lamp.

**Q: Can the battery be replaced or do I need to buy a whole new device?**
A: This device uses a standard 9V battery which is easily replaceable by opening the tool free back panel.

**Q: Why has Amazon reduced availability for this item as it is an essential item for the health of reptiles. Without this the animal may suffer and die?**
A: This is a one of a kind item that is in extremely high demand that often sells out frequently not only here on Amazon but also in reptile stores as well.

**Q: How good is this meter for detecting UVA rays which can penetrate Through the house window?**
A: This meter will focus on the total sunburning energy from both UVA and UVB. Since the amount of sunburning UVA coming from a window will be close to index 0, you may prefer using our indoor UVA Solarmeter 4.2 instead. Instead of measuring sunburning UVA, this meter will measure the total UVA that comes through your window.

### ⭐⭐⭐⭐⭐ Absolutely a great investment for any reptile owner
*by M***S on June 1, 2020*

I am so so happy I decided to invest in one of these and can’t 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 don’t 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 wasn’t 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 it’s expensive, but this is one you should definitely consider! It’s a one time investment that you’ll 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.
