■ The tripod stands for easy installation and moving
■ Outputting measured WBGT index, and save the data into PC Data logging available.
■ Remote monitoring between a gymnasium and a staff room

Regarding WBGT
WBGT (Wet Bulb Globe Temperature) is the heat index that is measured under consideration of three parameters i.e. humidity, radiant heat, and temperature, which effect the heat balance of human body.

These parameters are calculated by measuring three types temperature sensors, Dry, Wet, and Globe bulb temperature. Recently, this index is widely used to protect from heat stroke in sport and work environment.
