Thermal comfort is a crucial factor in terms of a person's physical and mental capabilities – and should be ensured through regular measurements of the individual parameters directly at the workplace.

In combination with an appropriate measuring instrument, the globe thermometer (thermocouple type K) enables standard-compliant determination and checking of the radiant heat parameter. For example, if a significant temperature difference between the ambient and globe temperature is detected, the cause could be high solar radiation through the window.

The hollow sphere has a diameter of 150 mm and there is a thermocouple type K at its centre for measuring the temperature.
