Comfort temperature measurement can be obtained by taking into account the radiant effect of surfaces within the controlled space. The comfort temperature is specified as the average of the conductive temperature and the radiant temperature. The TT-BB is a low-cost black-bulb temperature sensor used to measure radiant heat in indoor spaces. The units contain a high-quality thermistor or platinum element.
