HT30: Considers the effects of temperature, humidity, and direct or radiant sunlight. Experience the Extech Advantage
The wet-bulb temperature is the temperature read by a thermometer covered in water-soaked cloth (wet-bulb thermometer) over which air is passed. At 100% relative humidity, the wet-bulb temperature is equal to the air temperature (dry-bulb temperature) and is lower at lower humidity.
Relative humidity can be measured using a psychrometer. It has two thermometers, a wet-bulb thermometer and a dry-bulb thermometer.
This calculator shows the inter-relationship of air temperature and moisture content with dew point and wet-bulb temperature as measured by a psychrometric thermometer.

The Wet Globe Kit pictured (NSN 6665-01-381-3023) utilizes the WBGT index to measure the potential heat stress risk. Temperature and humidity are generally monitored to evaluate risk, however the WBGT Index also accounts for the impact that direct sunlight has on the subject.
The wet-bulb temperature is the reading registered by a temperature sensor placed in a moist gas stream and covered with a wetted cloth or wick.
