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
