Jerry,
thanks for the variety of tests and units.
I'm interested in how the RMYoung does, so run it awhile and if you can on sunny vs. cloudy days.
thanks for doing the work. Nice unit, I followed the link, and seems as good as it can get. I wonder if their fans burn out as fast as the Davis ones do?
Did Campbell Scientific make a funny looking thing that had a big bulge on one end and a horizontal white tube with a 45 degree angle cut on one end? The 'Big Boys' have the bucks to do the engineering and research, so I'm wondering how well they work compared to the amateur and low end pro stuff we use, and you are the only one who I recall has tested this so please graph and publish and discuss, just so we know.
