Excerpt from Technical Thermometry: Electrical Resistance Thermometers, Thermo-Electric Thermometers, Fery Radiation and Absorption Pyrometers, Continuous Temperature Recorders, Electrical Resistance Furnaces, Etc Some measure of the expansion that has taken place in the Thermometric Department of our Works can be obtained by comparing the size of the 1904 edition of Technical Thermometry with the present work. Great efforts have been made to keep this book within convenient limits, but nothing smaller would suffice for the mere enumeration of our productions with the briefest and most concise explanatory notes. By means of the F ery Radiation Pyrometer accurate measurements of very high temperatures have now been brought Within the reach of industrial concerns, this Pyrometer having been brought to a great degree of perfection and simplicity. Manufacturers of Porcelain, Glass and Stone-ware need no longer rely upon the old crude and inaccurate methods. The value of the radiation method has been enhanced by the production of a simple and reliable method of recording the measurements. In the department of Resistance Thermometry, interchangeability between thermometers has greatly increased the convenience of the instruments, and reduced the adjustments needed.
