Abstract
The instrument comprises means for measuring the ambient air temperature and providing a first signal proportional to the temperature, means for providing a second signal proportional to the non-evaporative rate of body heat loss in K Cal./m.sup.2 hr, and means for providing a third signal representative of the thermal insulation resistance of still air outside of clothing. Means is also included for measuring the fraction of full sunlight intensity reaching a person wearing the clothing, and for providing a fourth signal representative thereof, and further means for providing a fifth signal representative of the absorptance of the clothing. Further means adds the first signal to the product of the second and third signals and to the product of 230 and the third, fourth and fifth signals and substracts the product of 0.18 and the second signal, and provides an output signal, which is representative of the still shade temperature.
