Lord Kelvin. LOC. Lord Kelvin invented the Kelvin Scale in 1848 used on thermometers. The Kelvin Scale measures the ultimate extremes of hot and cold. Kelvin developed the idea of absolute temperature, what is called the  Second Law of Thermodynamics , and developed the dynamical theory of heat.
Finally, Celsius proposed a method of calibrating a thermometer: 1  Place the cylinder of the thermometer in melting ice made of pure water and mark the point where the fluid in the thermometer stabilises. 2  In the same manner mark the point where the fluid stabilises when the thermometer is placed in boiling water vapour.
