Wet Bulb Globe Heat Stress Meter with Color Coded Display, NIST

Wet Bulb Globe Heat Stress Meter with Color-Coded Display & NIST Traceable Certification

Eliminate the guesswork and enhance workplace safety with our advanced Wet Bulb Globe Heat Stress Meter. This essential tool is designed for accurately assessing the potential for heat-related stress in any environment, from industrial settings to athletic fields.

Instant, At-a-Glance Heat Stress Alerts What sets this meter apart is its unique, multicolor LED backlight display. These bright lights correspond directly to OSHA's established heat stress alert levels, providing an immediate visual warning when conditions become hazardous. Management and workers can instantly recognize when the heat index enters cautionary, moderate, high, or extreme risk zones. This visual alert system, paired with an optional audible alarm, provides a dual-layer of protection, empowering proactive measures to prevent heat-related injuries and illnesses.

Comprehensive Environmental Monitoring This meter provides a complete picture of thermal conditions by measuring and calculating:

• Wet Bulb Globe Temperature (WBGT): The most crucial measurement for heat stress, calculated for both direct sunlight and shade.
• Ambient Air Temperature (TA): Displays current, maximum, and minimum air temperatures.
• Black Globe Temperature (TG): Measures the radiant heat from sources like the sun or machinery.
• Relative Humidity (RH): Indicates the moisture content in the air.

Additional features include a data hold function to freeze readings on the screen and a low battery indicator to ensure you're never caught without power.

Data Logging and Analysis For in-depth analysis and record-keeping, this model can stream data directly to a computer. Simply use the optional USB Cable (#840054) and Data Acquisition Software (#840052) to monitor conditions in real-time or log data for compliance reporting.

Ready for Immediate Use The meter arrives ready to deploy, complete with clear instructions, 4 AAA batteries, and an integrated screw for easy tripod mounting.

NIST Traceable Certification This meter includes a Certificate of Compliance, verifying that it has been tested in our in-house lab using standards traceable to the National Institute of Standards and Technology (NIST). The certification covers the Relative Humidity & Air Temperature functions, confirming the meter meets or exceeds all published specifications. Your purchase includes complete documentation, including the unit's serial number, a certification label, and the detailed certification testing report.
