The globe thermometer from Testo is designed for the accurate and standard-compliant measurement of radiant heat – an essential parameter in determining thermal comfort in workplace environments. Meeting the requirements of ISO 7243, ISO 7726, DIN EN 27726 and DIN 33403, this instrument plays a key role in evaluating conditions that impact physical wellbeing and productivity.

Equipped with a type K thermocouple at the centre of a 150 mm hollow sphere, the globe thermometer measures radiant temperature within a range of 0 to +120 °C. When used in conjunction with a suitable measuring instrument, it enables precise analysis of thermal radiation. A notable difference between ambient and globe temperatures can indicate high exposure to radiant sources, such as direct sunlight, prompting necessary adjustments to workplace conditions.

This globe thermometer is a practical tool for professionals in occupational health, HVAC and indoor climate assessment, helping to ensure that workspaces remain comfortable and compliant with key comfort standards.
