Extension-4 is a sensor bar for calculating WBGT index. It must be used to determine which region of the body is most affected during working hours. In conjunction with the Protemp-4 Heat Stress Monitor, Extension-4 can be connected in series with up to 4 units at different heights such as chest, abdomen and legs to determine the region of the body most affected or horizontally by drawing a measurement perimeter.
