  • Measures ambient temperature, humidity, wet bulb temperature, black globe temperature, WBGT (wet bulb global temperature), heat stress index, dew point and pressure
  • Heat Stress Index measures how hot it feels when humidity is combined with temperature, air movement and radiant heat
  • Black Globe Temperature (GT) monitors the effects of direct solar radiation on an exposed surface
  • In/Out function displays the WBGT value with or without direct sun exposure
  • Multi-line backlit LCD display simultaneously displays 4 measurements—maximum, minimum, average and data hold functions
  • Internal memory stores up to 99 measurements
  • User selectable unit of measure (°F or °C)
  • User-adjustable WBGT threshold alarm (audible)
  • Tripod mountable for long-term monitoring
  • Low battery indicator and auto shut-off after 15 minutes
  • Includes: R6200 WBGT Heat Stress Meter, NIST Certificate with full Data and Uncertainties and Batteries
  • Items with calibration certificates are non-returnable and non-refundable due to the limited validity of the certification
