WBGT Meters – Accurate and Reliable Heat Stress Monitoring

WBGT meters (Wet Bulb Globe Temperature) are essential instruments for assessing the heat stress index, which measures the impact of heat on the human body under various environmental conditions. This index combines factors such as air temperature, relative humidity, solar radiation and air movement, providing a comprehensive and reliable picture of heat exposure levels.

Designed for use in industrial, occupational and outdoor environments, WBGT meters are widely used by professionals in health and safety, environmental engineering and occupational hygiene. These instruments help to prevent health risks such as heat fatigue, dehydration and heatstroke, ensuring safe working conditions and compliance with health and safety regulations.

What is the WBGT Index?

The WBGT (Wet Bulb Globe Temperature) index was developed to quantify the thermal load the human body experiences in a given environment. It is based on three key measurements:

• Natural wet bulb temperature (Tnwb) – reflects the effects of humidity and ventilation;
• Globe temperature (Tg) – measures the influence of solar radiation and hot surfaces;
• Dry bulb temperature (Ta) – indicates the ambient air temperature.

From these parameters, the WBGT meter automatically calculates the heat stress index, enabling technicians and safety managers to make informed decisions regarding work–rest cycles, hydration, and safe exposure limits.

Applications of WBGT Meters

WBGT instruments are suitable for a wide range of applications:

• Occupational safety and hygiene: heat monitoring in factories, construction sites, foundries and mines;
• Sports and outdoor events: controlling thermal conditions during training, competitions and endurance events;
• Environmental and meteorological research: studying temperature and humidity variations;
• Emergency services and defence sectors: assessing heat stress during operations and training.

Thanks to their precision and reliability, WBGT meters help organisations comply with international standards, such as ISO 7243, and national health and safety regulations related to heat exposure in the workplace.
