Description

HTC HD-01 WBGT Heat Stroke Meter – Real-Time Heat Stress Monitoring, Worn on Your Arm

The HTC HD-01 is a lightweight and portable WBGT (Wet Bulb Globe Temperature) meter designed to continuously monitor heat stress factors in real time. Ideal for use in outdoor work environments, athletic fields, industrial sites, and military settings, this wearable device allows users to keep track of ambient temperature, humidity, black globe temperature, and the combined heat stroke index—crucial measurements for preventing heat-related illnesses.

Wearable and Safe for Long-Term Monitoring

Lightweight and ergonomically designed, the HD-01 can be worn comfortably on the arm using an adjustable strap. This hands-free setup ensures the device stays in place and isn’t affected by body temperature, providing accurate readings even during physical activity or in hot environments. It’s a practical solution for technicians, supervisors, and safety personnel who must monitor environmental conditions while on the move.

Complete Heat Stress Parameters in One Device

The HTC HD-01 goes beyond basic indoor environmental sensing by measuring:

• Air Temperature, with a range of 0 to 50 °C (32 to 122 °F), a resolution of 0.1 °C, and accuracy of ±0.6 °C (20–40 °C) or ±1.0 °C otherwise

• Black Globe Temperature, ranging from 0 to 80 °C (32 to 176 °F), with the same resolution and accuracy standards

• Relative Humidity, between 20% and 90% RH, with 0.1 % resolution; accuracy is ±5 % (30–80 % RH) or up to ±10 % outside that range.

• Wet Bulb Globe Temperature (WBGT), displayed with 0.1 °C resolution and ±0.2 °C accuracy, calculated per international guidelines including ISO 7243, OSHA, Sports Medicine Australia, and Japanese occupational health standards.

Intelligent Alerts and Visual Feedback

To help users stay safe, the HD-01 features a programmable alarm with adjustable volume levels (75 dB, 65 dB, or mute) and a red LED warning indicator. It supports four danger-level thresholds and provides both audible and visual alerts when conditions exceed safe heat stress levels. Its sampling update interval—every 20 seconds—ensures users receive timely notifications.

Durable and Long-Running Performance

Powered by just two AAA batteries (1.5 V), the device achieves a long battery life of up to six months under normal usage conditions. Its compact form factor (117 × 59 × 45 mm) and lightweight construction (~95 g, including batteries) make it highly portable and unobtrusive during continuous monitoring.

Practical, Reliable, Standards-Based Functionality

The HD-01 displays WBGT, air temperature, and relative humidity simultaneously, allowing for easy interpretation of complex heat stress data. Designed for wearable use, it’s immune to interference from the wearer’s body heat and remains accurate even when worn against the skin. Built to meet recognized health and safety recommendations, this meter assists in preventing heat exhaustion in environments with high temperature, humidity, or radiant load.

Ideal Application Areas

This heat stroke meter is essential for:

• Outdoor construction, infrastructure maintenance, and manual labor in hot conditions

• Athletic training, competitions, and sports zones where heat stresses pose health risks

• Industrial spaces such as foundries, kitchens, and manufacturing lines with intense radiant heat

• Military and first-responder training where personnel operate in extreme environmental conditions

• Laboratories, research facilities, or agricultural environments where temperature and humidity must be controlled

Key Highlights at a Glance

• Monitors air temperature, humidity, black globe temperature, and WBGT index

• Compact and wearable design with adjustable arm strap; unaffected by body heat

• Programmable alarms and LED alerts for clear, immediate warnings

• Long battery life of approximately six months using two AAA batteries

• Auto-sampling every 20 seconds for near-real-time data

• Compliance with heat stress standards (ISO 7243, OSHA, SMA, Japanese health guidelines)

Conclusion
The HTC HD-01 WBGT Heat Stroke Meter combines portability, precision, and safety in a single, wearable instrument. Its multi-sensor capabilities and intelligent alerts make it an indispensable tool for anyone exposed to heat-intensive environments. Whether used by athletes, workers, or outdoor professionals, the HD-01 helps preserve health, enhance safety, and provide peace of mind in challenging conditions.
