Features Heat Stress Index measures how hot it feels when humidity is combined with temperature, air movement, and radiant heat Black Globe Temperature (TG) monitors the effects of direct solarradiation on an exposed surface In/Out Function displays the WBGT value with or without direct sun exposure Specifications Wet Bulb Globe Temperature (WBGT): 32 to 122°F (0 to 50°C) Black Globe Temperature (TG): 32 to 176°F (0 to 80°C) Air Temperature (TA): 32 to 122°F (0 to 50°C) Humidity: 0 to 100%RH Dimensions: Meter: 10 x 1.9 x 1.1" (254 x 48.7 x 29.4mm) Ball: 1.6" dia, 1.4" high (40mm diameter, 35mm high) Weight: 4.8oz (136g) The HT30 Wet Bulb Globe Temperature (WBGT) measurement considers the effects of temperature, humidity and direct or radiant sunlight. It can also determine Heat Stress Index which measures how hot it feels when humidity is combined with temperature, air movement, and radiant heat. Black Globe Temperature (TG) monitors the effects of direct solar radiation on an exposed surface. An in/out function displays the WGBT value with or without direct sun exposure. Additional features include Auto Power Off with override and a built-in RS-232 interface. Complete with 2 AAA batteries.
