eupatheoscope

An instrument designed by A. F. Dufton in 1929 to record the warmth of a room from the point of view of comfort. It consists of a blackened hollow copper cylinder heated by a carbon filament and a metal filament lamp, which are controlled by a thermostat to maintain a temperature of 75°F. The power used is interpreted in terms of equivalent temperatures.
