I just want to know what kind of thermometer they put into the plasma to measure the temperature. It must have been made of ice or something to not burn up.

They usually measure extreme high temperatures differently, not with thermometers based on heat expansion of materials. They measure heat radiated, not conducted.

In plain English, they look at it with a heat camera, like you see on TV they patrol borders with.
