Hi everyone
Have you ever wondered how hot it is in a furnace that melts cast iron? I made a video about how I measured my furnace temperature using a "R" type wire pyrometer. One wire is pure platinium and the other wire is 90% platinium/ !0% Rodium. Both wires are welded together at one end and the other two ends are connected a millivolt meter recalibrated to read in Celsius. It will read up to 1770 C before the wire begins to melt. This wire is very expensive so it will not be on top of the shopping list for the home foundryman. [ame="http://youtu.be/h3YXRl2LGMk"]http://youtu.be/h3YXRl2LGMk [/ame]
