PT100 What is the material of the heat resistance

The formal manufacturers use sterling silver as a lead. There are also pure nickel and copper -plated silver. The temperature resistance of copper -plated silver is not more than 300 degrees. If you burn the lighter, you know that the sterling silver is getting white and whiter, and the other burned are dark.
