• Wet Bulb Globe Temperature (WBGT) is commonly used as a guidance for environmental heat stress to prevent heat stroke during physical exercise or while at work.
• WBGT as a measurement method to determine heat stress given to human body at work in thermally harsh environment is specified in ISO 7243 under the title; Hot Process & Environments – Estimation of the heat stress on working man, based on the WBGT-index (wet bulb globe temperature).
• Below chart of WBGT-index shows the criterion of heat stress warning specified by Japan Athletic Society in order to prevent heat stroke:
  

  WBGT[°C]	Types of warning and required rest
  Below 21	Safe (needs occasional supply of water)
  21 – 25	Note (needs immediate supply of water)
  25 – 28	Caution (needs to take rest)
  28 – 31	Warning (Stop active physical exercise)
  Above 31	Dangerous (Cancel physical exercise)

• Maximum 1,000 sets of data can be stored, and continuous measurement by automatic sampling is possible.
• Measuring result data can be printed out by the optional printer.
