A practical manual on the basic sensors for measuring temperature, simplifying the principles for the incidental user, yet providing in-depth information for those who apply them in a wide range of situations. Focuses on the thermocouples, circuits, and hardware of the kind ordinarily used in routine laboratory and industrial practice. First published in 1970, and most recently in 1980; the fourth edition is completely reworked to account for the new international temperature scale, the IT-90.
