Decided after seeing the new Egg-o-Meter thermometer, a water weasel simulator type, I decided that I would try to make my own. Used a plastic egg, filled with silicone (smell has dissipated as it cured) and one of my AcuRite probe thermometers. Drilled a hole in the aircell end of the plastic egg, added the probe, filled with silicone and sealed up the egg. Just tested it. Put probe from my best AcuRite in the water weasel and the probe from my other one in my homemade Egg-o-Meter. The probes have always read very close to each other on those two units. Placed them close to each other in my Hovabator (not the one with eggs in it) and waited. The water weasel consistently reads 3/10 of a degree higher than my homemade Egg-o-Meter, so they are very close. And this new one can be placed right in one of the turner slots just like any egg would be. There is no silicone smell in the bator, which was my concern, the fumes from it as it cured, but I wouldnt put it in with actual eggs till it had no smell.
