Globe thermometer for measuring the radiant temperature
The standard globe thermometer consists of a black-painted copper sphere with a diameter of 150 mm and a thickness of 0.4 mm. It contains a thermometer with its bulb at the center of the sphere. This sensor is described in the ISO7726 standard. Main scope of the radiant temperature measurement in meteorological applications is the possibility of estimate the Mean Radiant Temperature (Tmrt) which is one of the most important meteorological parameters governing human energy balance and the thermal comfort of man in micrometeorological measurements.
