WBGT-101 - Heat Index Meter

(not CE conformed)

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.
