Physiological Heat Exposure Limit, or PHEL, is the U.S. Navy’s method for managing occupational heat stress using work-rate based heat exposure curves. These curves are built around WBGT, which means accurate environmental heat measurement is the foundation of PHEL-based heat safety decisions.
For teams operating in hot environments, WBGT monitoring helps translate heat conditions into clear action. A WBGT monitor can support work-rest planning, early intervention, and safer scheduling by showing when heat exposure is approaching unsafe levels.
EnviroLive’s WBGT-1000 Series is designed for that kind of real-world use. It measures WBGT, heat index, and ambient temperature, while cloud-ready remote monitoring software logs readings automatically so safety teams can review time-stamped data, track trends, and document controls taken during heat events. That makes it easier to support a PHEL-style heat stress program with reliable data.


If your goal is to improve heat safety and reduce risk, WBGT monitoring is a simple but powerful step. It gives crews and supervisors the information they need to make better decisions before heat stress becomes a problem.
The WBGT-1000 monitor and remote monitoring software help teams manage PHEL-style heat stress programs by capturing time-stamped WBGT, heat index, and ambient temperature readings for review, reporting, and safer work decisions.
Consistent
By monitoring the thermal footprint of the production floor and external areas, the device ensures that every shift operates under the best environmental conditions.
Reliable
Captures a full profile of the production environment, ensuring warnings of relative humidity and radiant heat stay within strict parameters.
Accurate
The WBGT-1000 Series provides detailed temperature readings, including humidity and radiant heat from machinery, preventing ambient interference and possible thermal degradation.
Through real-time telemetry, data is streamed directly to the dashboard, allowing for instant oversight of the entire facility from the central office, or any personal device.
The transition to data-driven heat safety marks a shift in how we manage the modern industrial environment. With EnviroLive’s WBGT-1000 Series‘s ability to monitor every zone of your facility from any device, you gain the transparency needed to mitigate risks before they impact your bottom line. Protect your team, preserve your assets, and maintain your competitive edge with a smarter approach to environmental awareness.
