Don't waste the money on the ZooMed meter. It is just a SolarTech brand meter with a ZooMed sticker on it.
Mathew Parks from Pangea took my advice in selling the 6.2 UVB meter on his site. Wow... looked it up on the site and the price seems to have jumped a bit. I thought I remember him offering them for about $145.... but here is the link to the meter on the site.
