Traceable Temperatures An Introduction to Temperature Measurement and Calibration J. V. Nicholas D. R. White New Zealand Institute for Industrial Research and Development Over one in five thermometers currently in use are out of calibration. This self-teaching text seeks to redress this situation by providing practical guidance on temperature measurement and calibration. Focusing upon recognised measurement procedures and international standards, the authors detail the operating and measurement principles for the four most common thermometers: platinum resistance, liquid-in-glass, thermocouples and radiation thermometers. Features include: The latest temperature information: including ITS-90 reference tables for thermocouples and platinum resistance thermometers. Detailed coverage of traceability: how to make traceable measurements and how to design, carry out and report calibrations. Identification of the main contributing uncertainties for a range of thermometers. Extensive advice on accuracy, with sections devoted to the recognition and treatment of errors. Technical information to complement the managerial guidelines of the ISO 9000 series QA systems. The systematic approach will assist those seeking accreditation along the lines of ISO Guide 25. lllustrative examples, detailed references and a full bibliography. Practising measurement engineers, scientists and technicians will find the authors' emphasis on quality concepts and modern instrument practice particularly valuable. Students on engineering courses and research workers will also find this comprehensive reference source appealing. Traceable Temperatures: An Introduction to Temperature Measurement and Calibration forms part of the Wiley Series in Measurement Science and Technology. Chief Editor: Peter Sydenham, Sensor Science and Engineering Group, University of South Australia. This series was founded to coincide with the recognition of measurement science and instrument technology as fields with their own scholarship and techniques.

'Practical Temperature Measurement' introduces the concepts of temperature and its measurement to engineers, physicists and chemists of all disciplines. The author describes the wide range of techniques and specific devices available for temperature measurement and provides guidance for the selection of a particular method for a given application. It is of value to engineering and physics postgraduates studying modules on instrumentation and process control and, in addition, for practical project work requiring an understanding of temperature measurement methods. For postgraduates and industrialists faced with the task of selecting a particular measurement method or sensor for an experiment, product or process, this text provides both thorough descriptions of the various techniques, as well as guidance for their selection.
