I have 4 thermometers in my LG incubator. It is a still air model with a home rigged computer fan circulating the air. My thermometers usually have 2 or 3 out of 4 that agree on the temp, but the 4th will read something way off. The thing is it switches which one does it. The Fluker one seems the worst at being off (but I can't figure out if one is reliable and the other arent). Or are the temps really 98.8, 99.5, 99.5, 102.3 Even when I put them side by side they vary. I'm so frustrated. I'm erring on the side of too low than too high, but I can't really tell what my temps are. I've kind of decided to average the 4 and go with that temp. Other people have the same problem? What do you do?
