TWL-1S Hest Stress Monitor measures air temperature (Ta), relative
humidity (%RH), globe bulb temperature (Tg) and wind speed (WS),
whereas wet bulb temperature (Tw) is derived from Ta, %RH at sea
level atmosphere pressure.
WBGT (Wet Bulb Globe Temperature) and TWL (Thermal Work Limit)
can be calculated on the device. WBGT is derived from Tw, Tg or/and
Ta wheather indoor or outdoor. TWL is derived from Tw, Tg, Ta, WS
