TM-288 Heat Stress WBGT Meter
Measure the WBGT, black-globe temp. (TG), Air temp. (TA), humidity (%RH).
Application
As the Holy Infant, the temperature increasingly rises.
The chance of heatstroke increases dramatically in the moist heat environment.
This product, measuring in WBGT, provides real-time alarm immediately so as to
prevent heatstroke in such the environment.
