Maxisafe - Heat Stress Monitor Wristband

Heat Stress Monitor Wristband. Wearable heat-stress monitoring device for early warning of heat-related illness risk on hot worksites.

Real-time individual heat risk detection for workplace safety.

The Canaria Plus Heat Stress wristband is a wearable device designed to detect personal heat risk in real time before symptoms occur.

Unlike traditional methods that rely on environmental measurements such as temperature or WBGT, this device monitors physiological heat accumulation, providing a more accurate indication of how a worker's body is responding to heat.

How it works

The device uses a validated algorithm to estimate heat accumulation in the body, correlating closely with core body temperature trends.

Rather than reacting to external conditions, it identifies when an individual worker is approaching a critical heat threshold - providing an early warning window before peak physiological stress occurs.

This enables:

• Timely rest and recovery decisions
• Reduced reliance on subjective symptoms
• Improved consistency in heat risk management
