ABSTRACT:
An apparatus for sensing temperature, humidity, air movement and mean radiation so that those factors which effect human comfort may be correlated to determine effective temperatures. The apparatus includes a thermometer which is capable of simultaneously sensing dry bulb temperature, wet bulb temperature and mean radiation to produce a temperature reading indicative of the combination of those factors. Wind speed indicators are provided for use with temperature correction charts so that the air movement factor can be correlated with the temperature, humidity and mean radiation factors to arrive at a comfort index, or effective temperature.
