| Heat Stress WBGT Meter |
|
| Wet Bulb Globe Temperature (WBGT) considers the effects of temperature, humidity and direct or radiant sunlight |
 |
- 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
- Air Temperature (TA) plus Relative Humidity (RH)
- Selectable units of °F and °C
- In/Out Function displays the WGBT value with or without direct sun exposure
- Auto Power Off with override
- Built-in RS-232 interface with optional Windows® compatible software
- Complete with two AAA batteries
