Heat Stress

WBGT Meter

Extech’s Heat Stress WBGT (Wet Bulb Globe

Temperature) Meter accurately determines the Heat

Stress level (how hot it feels outside) by factoring a combination of humidity, temperature, air movement, and direct solar radiation. These factors all affect how hot our bodies get, as well as our ability to cool down.

It’s perfect for monitoring the Heat Index on hot humid days to prevent heat stroke during road or building construction, outdoor activities, sporting events, or in the workplace.

Features

•

Uses a capacitance sensor to accurately measure

Wet Bulb Globe Temperature (WBGT), Black Globe

Temperature (TG), Relative Humidity (%RH), Air

•

Temperature (TA), Wet Bulb (WT) and Dew Point (DEW)

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 solar radiation on an exposed surface

• In/Out function displays the WBGT value with or

• without direct sun exposure

WBGT high/low alarm settings

• Memory stores up to 50 readings

• Backlit LCD

• Min/Max and Data Hold

• Low battery indicator

• Auto power off with disable

• Complete with 9V battery and hard carrying case
