Radiator, thermogram footage. Thermography records the temperature of surfaces by detecting long-wavelength infrared radiation. The colours show variations in temperature. The scale runs from white (warmest), through yellow, orange, red and purple to blue (coldest). A colour-coded temperature scale is at right, ranging from 20 degrees Celsius (dark blue) to 56 degrees Celsius (white). In this footage, the radiator starts off radiating heat at a temperature of around 52 degrees Celsius, and then cools to room temperature.
