Excerpt from High Temperature Measurement by Electric Means The accurate measurement of high temperatures has come to be a very essential feature of many industrial pro cesses. The pyrometer makes it possible to reproduce with precision any temperature that has been found to yield the best results in Operations requiring careful heat treatment. In the making of tinted glass, for example, the preper regu lation of the temperature of the furnace is necessary to pre vent burning out the color. Instead of depending upon the workman to judge of the condition of the material with his eye, the manufacturer gives instructions to maintain the heat at a certain temperature, knowing then that the output will be of a certain uniform grade. In this manner the variable human element is eliminated and waste prevented. The temper ing of tools, the burning of ceramic products, the Operation of gas producers, the manufacture of iron and steel and the annealing of castings are a few examples of processes that may be carried on to better advantage with the aid of refined methods of measuring high temperatures. The recording pyro meter is rapidly coming into use as an efficient means of eu pervising processes requiring heat treatment.
