Wet Bulb Globe Temperature Index Meter (WBGT-302)

Wet Bulb Globe Temperature Index
Also known as the WBGT index, it refers to a fundamental parameter for comprehensively evaluating the thermal load on the human body in a working environment.
Outdoor WBGT = Natural Wet Bulb Temperature (°C) × 0.7 + Globe Temperature (°C) × 0.2 + Dry Bulb Temperature (°C) × 0.1
Indoor WBGT = Natural Wet Bulb Temperature (°C) × 0.7 + Globe Temperature (°C) × 0.3
