  • Extech HT200 Heat Stress WBGT (Wet Bulb Globe Temperature) Meter

The HT200 is a Heat Stress WGBT Meter which enables accurate measurements for Wet Bulb Globe Temperature (WGBT), Black Globe Temperature (TG), 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. Stores up to 50 readings.

Features:

  • Meter accurately determines the Heat Stress level by factoring a combination of humidity, temperature, air movement, and direct solar radiation
  • 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)
  • 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
  • Min/Max, Data Hold, Auto Power Off, Low battery indicator
  • Comes with 9V battery and hard carrying case
