I am looking for a digital thermometer/hygrometer that i can put into the incubator with my eggs as a back-up. I have looked at Oregon Scientific and Acu-Rite. They both have pretty good reputations, but I have bought a few of each to get a mean and found that there are variances. These units are well within my price range as they are from $12 to about $30. I need these units to be small so it doesn't take up valuable space for eggs. Does anyone have recommendations for combination units like these? I appreciate your help.
