Functions:
- Heat stress index (WBGT), temperature. humidity in one handy meter
- Measures:
- Wet Bulb Globe Temperature (WBGT) -a commonly used heat
stress indicator that considers the effects of temperature, humidity and
radiant energy.
- Black Globe Temperature (TG) - measured by the black globe
thermometer, which monitors the effects of direct solar radiation on an
exposed surface
- IN/OUT: Represent the measuring environment that is with or
without direct sun exposure and display corresponding WBGT values using
the following equations:
- Indoor/outdoor no sun: WBGT=0.7 WB + 0.3 TG
- Outdoor or full sun: WBGT=0.7 WB + 0.2 TG + 0.1 TA
- Air Temperature (TA)
- User calibratable
- Audible alarm for thermal condition monitoring
- Low battery indicator
- Can be switched between °F/°C
- Sensor protecting cover
- Tripod mountable
- RS-232 output (9600 BPS, 8 data bits, no parity)
