Heat illness can bring danger to human health and even lead to death. This phenomenon is on the rise!
. , : >Athlete deaths caused by overheating have increased. In the hot summer, there are frequent reports of young or old athletes suffering from serious illnesses due to the high temperature and finally falling ill. While our military training institutions are trying to keep our soldiers healthy, they must also train them to cope with the extreme heat of Iraq and Afghanistan. Every year, countless outdoor workers fall ill due to heat stroke during work, and some even die as a result. Such reports are common. It is dedicated to keeping outdoor workers safe from heat illness. Key to this plan is the ability to accurately locate and measure thermal stress conditions. The thermal stress tracker from R brings us good news.
. , : >Human thermal stress comes from the comprehensive air temperature and humidity of multiple environmental factors, as well as thermal radiation from the sun and the ground. The cooling effect of wind or airflow can keep these factors in relative balance. If you've ever been in the shade next to a sweltering parking lot, you'll know that condition assessment must be done where people are. The most common composite measurement used to determine appropriate thermal stress is wet-bulb temperature (B). The American College of Sports Medicine, the American Conference of Governmental Industrial Hygienists, and the U.S. Military have published critical thresholds () or conditional reference guidance based on dress conditions and participant suitability, as well as activity level and hydration. .
. , : >r The thermal stress tracker provides B measurements in the dry state.

So far, most precision B measurement tools are large, bulky and difficult to use (distilled water is required), and expensive. A small black bulb thermometer is added to the r Pocket Weather Tracker's certified sensor suite, and advanced algorithms are built in to allow the device to calculate B's value. The calculated value is within .degree Celsius of the measured value for the entire B component. r The Pocket Thermal Stress Tracker can be carried in your pocket or in its carrying case. Expose the device to air for a few minutes and it will accurately measure dry B.
. , : >and other critical measurements
. , : >r also displays the thermal exposure operating limits ( ), another recognized tool for composite thermal stress prediction. For B and R, when the external conditions reach the warning or dangerous value, r will display a warning message on the immediate screen to clearly inform that heatstroke prevention measures must be taken immediately. Users can define their own clothing level so that r can perform special functions even when using heavy protective devices. Because such protective devices tend to make thermal stress stronger. r can also display values such as natural wet bulb temperature, black bulb temperature, and mean radiant temperature).
. , : >R’s options and accessories
. , : >Using the r blade mounting accessory, the r Thermal Stress Tracker can be mounted on a tripod for long-term monitoring and recording of thermal stress. Condition. You can choose to use the Br wireless data transmission device to transfer the recorded data to a computer or smartphone for subsequent review.
