Metravi Wet Bulb Globe Temperature Meter, WBGT

The Metravi Wet Bulb Globe Temperature (WBGT) Meter is a specialized device used to measure the WBGT index, which is an indicator of heat stress in environments where high temperatures and humidity levels can pose health risks to individuals, particularly those engaged in physical activities or working outdoors. Here are the key features and functions of such a meter: Measurement Parameters: The WBGT meter typically measures three key parameters: Wet Bulb Temperature (Tw): Indicates the temperature of a thermometer bulb covered in a wet fabric exposed to the air. Globe Temperature (Tg): Measures the temperature inside a hollow copper sphere, simulating the heat absorbed by a human body. Dry Bulb Temperature (Td): Represents the ambient air temperature measured by a conventional thermometer. Calculation of WBGT Index: The WBGT index is calculated using a formula that incorporates the three measured parameters. This index provides an indication of the combined effects of temperature, humidity, and radiant heat on human physiology. Display: The meter typically displays the measured values of wet bulb temperature, globe temperature, dry bulb temperature, and calculated WBGT index. Some models may have additional features such as data logging and graphical displays. Portable Design: WBGT meters are often designed to be portable for ease of use in various environments. They may feature rugged construction and ergonomic designs suitable for field use.
