The calibration of a thermocouple consists of the determination of its electromotive force (emf) at a sufficient number of known temperatures so that, with some accepted means of interpolation, its emf will be known over the entire temperature range in which it is to be used. The process requires a standard thermometer to indicate temperatures on a standard scale, a means for measuring the emf of the thermocouple, and a controlled environment in which the thermocouple and the standard can be brought to the same temperature. Some of the more commonly used techniques for accomplishing such calibrations will be discussed in this chapter. Much of this material is based upon National Bureau of Standards Circular 590, Methods of Testing Thermocouples and Thermocouple Materials, and the calibration methods appearing in Chapter 19, Part 3, Temperature Measurement, of the American Society of Mechanical Engineers Power Test Codes.

Thermoelectrics is the science and technology associated with thermoelectric converters, that is, the generation of electrical power by the Seebeck effect and refrigeration by the Peltier effect. Thermoelectric generators are being used in increasing numbers to provide electrical power in medical, military, and deep space applications where combinations of their desirable properties outweigh their relatively high cost and low generating efficiency. In recent years there also has been an increase in the requirement for thermoelectric coolers (Peltier devices) for use in infrared detectors and in optical communications. Information on thermoelectrics is not readily available as it is widely scattered throughout the literature. The Handbook centralizes this information in a convenient format under a single cover. Sixty of the world's foremost authorities on thermoelectrics have contributed to this Handbook. It is comprised of fifty-five chapters, a number of which contain previously unpublished material. The contents are arranged in eight sections: general principles and theoretical considerations, material preparation, measurement of thermoelectric properties, thermoelectric materials, thermoelectric generation, generator applications, thermoelectric refrigeration, and applications of thermoelectric cooling. The CRC Handbook of Thermoelectrics has a broad-based scope. It will interest researchers, technologists, and manufacturers, as well as students and the well-informed, non-specialist reader.

Thermocouples: Theory and Properties provides the basis for the examination and explanation of thermoelectric phenomena and their correlations with other physical properties. These results are applied and account for the properties and deviations of commercial materials in the temperature ranges of most common industrial usage. This book is written expressly for non-scientists and is an effective tool for the busy technician or engineer working with thermoelectric thermometry in metallurgical, chemical, petroleum, pharmaceutical, and food processing areas. It is also beneficial for use in quality control and research and development applications. The book provides more than the usual superficial presentations of thermoelectric properties; it explains the ""why"" as well as the ""how"" and ""what"" of thermoelectric behaviors. These answers are important because only a suitable combination of theory and practice can lead to the understanding required for optimum thermometric applications under the multitude of applications encountered in industry and science.
