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?
I am setting my first batch as we speak. two thermometers are close the other two live in different worlds. Has not stabilized yet keeping my fingers crosses
It is a shame that with all the tech. now a days we can"t buy thermometers from china that read alike even in the same hole, maybe Mexico can do better.
The temperature is different in different places in the incubator. The reading sensor is in different positions on different thermometers as well. I can sympathize with you on trying to figure out which is correct. The Best thing to do is place the all on a table outside the incubator and compare them to a mercury thermometer. I use the one to take my temperature. I go with the one that is closest to the mercury. The differences you are seeing is why many people use the water weasel. It give you a more constant temperature without fluctuations caused by the heat element going on and off.
