Hi
Does anyone have any experience of using one of these sunshine recording instruments, and any information on their accuracy. I have looked at their web site but it seems a bit dated, with most information relating to 2011-2012.

I happen to know the co-designer Alan Blake. He lives on the moors just outside Penzance.
Just click on 'contact'button

Stephen Burt did a fair bit of work comparing the Blake-Larsen results, you might want to contact him.
I would say Alan's a typical inventor, keeping a website up to date is somewhat down his priority list.
