This meter (Solartech Model 5.0) measure UVA/UVB and has a peak sensitivity of 390nm (IIRC).

No Vaugh, you weren't doing the razzing I was referring to...

Ultimately I'm going to try to apply it to my own tissues of course, but trying to get some sense of other people's tissues only seems natural. There will be 2 limits; a tissue that requires the most UV and one that requires the least. I'd like to know what the spread is.

The many questions & concerns perfectly highlight why doing a bit of investigation with a UV meter is needed; at the very least, to find some answers for them.

Last time I take advice from Robert Frost...
