## Questions & Answers

**Q: How do i decipher the reading on the machine ? i'd like to know the uv index but the machine gives a reading in the 100s. is there some kind of chart?**
A: Hello
The reading of iU2 is the radiation intensity of UVA and UVB. The unit is uw/cm2. 
Although it is not very accurate, it can be converted into uv index: 
uv index=0.005381 x reading.

For example, if the reading is 100 uw/cm2,  
    then uv index=0.005381 x 100 =0.5381

Hope the above can answer your question.
Thank you!

**Q: How accurate is this device?**
A: instructions on how to use and interpret the readings are incomplete or lacking.

**Q: What's the spectral response graph of this meter?**
A: Based on a relative response curve received from the manufacturer: imagine (linear scales) a profile that goes straight from about (6 units, 240nm) to (87.5 320nm) followed by a tapered line to (100, 360nm), followe by a rapid decrease to (0, 375nm)

**Q: Will this read how strong my uvb reptile**
A: UVB reptile?  I assume you forgot a word and are asking if the meter can read the intensity of a UVB reptile light.  The box states" iU2 Ultraviolet A/B Light Meter".   So it seems that the meter would be able to read the strength of your UVB reptile light, if it emanates UVB within the 240-370 nm spectrum, but I cannot guarantee that it will do what you need done.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works well even under low light conditions
*by G***H on November 25, 2019*

I've been looking for a UV meter for a while - most are junk. This one seems to work well - from bright sunlight to dim interior sources of UV. I'm able to measure exactly how much UV light makes it through windows, glasses, etc. I found most sunglasses block nearly all UV light. While car windows (especially side windows) dont block much. Really nice to get a quantitative number!

### ⭐ Waste of Money
*by R***S on August 25, 2023*

The instrument worked for one day. After that, the readout was zero. Even in the hot Texas sun, the instrument read zero. What a waste of money.

### ⭐⭐⭐⭐⭐ Useful to verify that glasses advertised as UV blocking actually do so.
*by G***O on July 31, 2018*

It allows me to verify that glasses advertised as UV blocking actually do so. I am at high risk for macular degeneration and need to limit how much UV hits my retinas. Easy to use.
