platinum resistance thermometer

[′plat·ən·əm ri¦zis·təns thər′mäm·əd·ər]
(engineering)
The basis of the International Practical Temperature Scale of 1968 from 259.35° to 630.74°C; used in industrial thermometers in the range 0 to 650°C; capable of high accuracy because platinum is noncorrosive, ductile, and nonvolatile, and can be obtained in a very pure state. Also known as Callendar's thermometer.
