Stopping at an estate sale before lunch, I scored a couple of new toys. One is a sling psychrometer, looking like the model 6500 here: http://www.americanweather.com/hygrometers.html#MODEL_6500_PSYCHROMETER The other is a smaller wall mounted unit by Taylor. I'd looked at psychrometers off and on for years, but didn't need one badly enough to pay the price of new. Gave $9 for the two of these. I do love estate sales... Ron N
