Heat stress monitors like the Casella MicroTherm allow consultants to determine the WBGT (Wet Bulb Globe Temperature) index of a given area.
The measurements provided by this index helps to ensure workers, athletes, pedestrians and consumers avoid the symptoms of heat stress related illnesses such as nausea and stroke.
Based on the data collected, the professional can determine how many if any breaks are needed, how often one should hydrate, and even make suggestions for proper work attire to avoid possible illness or even death.
Some instruments including the Casella MicroTherm are able to record results into a suitable format for compliance to OSHA and ISO recommendations.
