After much research and frustration, I believe I have found a great thermometer/hygrometer combo. It is called a Caliber III and my director of technical services "tested" it for me....and told me it was extremely accurate. (We are in the hardwood flooring business and humidity especially is important to proper manufacturing, installation and/or claims issues!!) The least expensive place I found it ($19) was at www.bargainhumidors.com (a cigar website of all places). It is relatively small and fit easily into my incubator. Is also easy to read and requires NO CALIBRATION. At any rate I hope this helps some of you.
