Abstract
The Wet Bulb Globe Temperature is a practical index of man's heat stress in hot environments. It is a composite measure of the four factors affecting thermal comfort in man, namely, air temperature, relative humidity, air movement and thermal radiation level. Several recent Canadian instruments designed for direct measurement of this index are described. Two of these are electronic meters, one using thermistors, the other silicon diodes as temperature sensors. Two others are fluid analogue WBGT computers based on the liquid-in-glass thermometer and requiring no electronics or power sources. Two computation aids - a WBGT nomogram and a wheel type calculator - that are useful for calculating the WBGT index from its component temperatures are also described.
