Heat Stress Sensor

HSS-100

Category:

Protect your workforce from heat-related risks withE4A's advanced Heat Stress Monitor - a cutting-edge device designed to help you manage heat stress with precision. Using Wet Bulb Globe Temperature (WBGT) measurements, this monitor provides real-time environmental readings that factor in temperature, humidity, and radiant heat.

More than just a sensor, it intelligently analyzes work conditions and offers clear guidance on individual cooling periods and recommended break schedules, promoting safe productivity in hot environments. Heat Stress Sensor ensures compliance with safety regulations and supports proactive health and performance management.

Optimized Break Planning
Analyzes exposure and workload to recommend personalized cooling period and rest breaks, reducing the risk of heat-related illness.
Real-Time Awareness
Delivers up-to-the-minute status updates and alerts, giving supervisors the insights needed to make fast, informed safety decision.
Productivity Protection
Helps maintain safe work rates without compromising performance by balancing environmental stress with proactive recovery strategies.
Regulatory Compliance
Supports adherence to OSHA, ISO, and industry heart stress guidelines with accurate, timestamped data for reporting and audits.
Simple Integration
Compact and wireless-ready, the WBGT Monitor intsalls quickly and fits into excisting safety systems with minimal setup.
Team Health Insights
Monitors heat stress exposure levels across the work environment to help managers ensure safe confitions and prevent overheating.
Data-Driven Decisions
Empowers organizations with accurate environmental data to support planning,training, and operational risk assessments.
Proactive Risk Reduction
Identifies hazardous heat conditions before they become critical, enabling early intervention and safer work environments.
