Thermometer and Hydrometer Question

So do you just set the little plastic thing down in the incubator or is there a metal thing connected to a wire that goes in?

I set the plastic thing down where I can see it through the window I don't use the one with the wire probe, I just use the white one, I think it has a magnet on the back of mine so it stays put on the wire floor!
