HD32.32 WBGT Index Measurement
Overview
HD32.2 Heat Stress Meter: Accurate WBGT Measurement in Hot Environments
The HD32.2 Heat Stress Meter is a reliable and portable thermal microclimate data logger designed specifically to measure the WBGT (Wet Bulb Globe thermometer temperature) Index in hot environments, adhering to ISO 7726 and ISO 7243 standards. With its advanced features and precise measurements, the HD32.2 ensures accurate assessment of heat stress levels to promote safety and well-being.
The HD32.2 Heat Stress Meter meets the demands of the South African environment, the flexibility with multiple probe options allows for the instrument to measure multiple parameters.
Key Features:
- WBGT Measurement: Measures the WBGT Index using the Globe thermometer temperature (Tg), Wet bulb with natural ventilation temperature (Tn), and Ambient temperature (T) dataset.
- Comprehensive Index Calculation: Based on the detected measurements, the HD32.2 can calculate both the WBGT(in) index in the presence or absence of solar irradiation, as well as the WBGT(out) index in the presence of solar irradiation.
- Probes for Accurate WBGT Measurement: The HD32.2 requires the following probes for WBGT measurement: Dry bulb temperature probe TP3207.2, Globe temperature probe TP3276.2, and Natural ventilated wet bulb temperature probe HP3201.2.
- Portable Design: The HD32.2 is the ideal portable version, perfect for on-the-go measurements. It is often used in combination with a table stand (small tripod) for added convenience and stability.
- Longer Duration Measurements: For extended measurement periods, we recommend the HD32.3A version, which includes a stable tripod for reliable and continuous monitoring.
- The HD32.2 provides accurate and comprehensive WBGT measurement to assess heat stress levels effectively. It is a valuable tool for a wide range of applications, including industrial workplaces, sports events, outdoor activities, and more. Prioritize the well-being and safety of individuals in hot environments with the HD32.2 thermal microclimate data logger.
Choose HD32.2 for reliable WBGT measurement. Stay safe in the heat.
