ABSTRACT:
A heat stress monitor comprised of a thermometer tube having at least a black globe-bulb and a wet-bulb therein and adapted to provide a direct reading of wet-bulb globe temperature (WBGT). The inclusion in the tube of a dry-bulb makes the monitor particularly adapted to measuring WBGT outdoors. The thermometer tube is in the form of a single tube and the bulbs are disposed in series therein with an extension part extending beyond the bulbs to permit a direct reading to be taken of the position of a thermally responsive medium in the tube.
