Wet Bulb Globe Heat Stress Meter SD Card Logger, NIST Certificate

Stay Safe and Productive: Introducing the Advanced Heat Stress Meter with SD Card Logging

Monitor Environmental Conditions with Precision: Protect your team and optimize performance with our state-of-the-art Wet Bulb Globe Heat Stress Meter. This robust device goes beyond basic temperature readings, providing comprehensive data crucial for assessing heat stress risks in any environment. It accurately measures and displays:

• Relative Humidity (RH): Understand moisture levels in the air.
• Air Temperature (TA): Standard ambient temperature.
• Dew Point Temperature: The temperature at which air becomes saturated with water vapor.
• Wet Bulb Globe Temperature (WBGT): The most reliable indicator of heat stress, accounting for temperature, humidity, wind speed, and radiant heat.
• Black Globe Temperature (TG): Measures radiant heat from direct sunlight or hot objects.

Seamless Data Logging and Analysis: Experience unparalleled ease in data management. Our meter records all measurements, along with precise sample times and dates, directly onto a standard SD (Secure Digital) memory card—just like a digital camera!

• Unlimited Storage: Simply swap SD cards for continuous, unlimited data collection.
• Effortless Transfer: The removable SD card makes transferring data to your computer a breeze. No special software or cables needed!
• Instant Excel Reports: Data is pre-formatted for direct import into Microsoft Excel, allowing for immediate analysis and reporting.
• Flexible Memory: Additional SD cards are readily available in various memory sizes to suit your needs.

Designed for Practicality and Performance: This isn't just a measurement tool; it's a complete heat stress monitoring solution built for demanding environments.

• Adjustable WBGT Audible Alarm: Set custom thresholds to alert you immediately when heat stress conditions become dangerous, enabling proactive safety measures.
• User-Friendly Features: Includes Min/Max record, automatic power-off to conserve battery, a low battery indicator, and a data hold function for easy reading.
• Exceptional Accuracy and Responsiveness: Delivers highly accurate readings with rapid response times, ensuring you get critical information quickly.
• Clear Visibility: Features a large, easy-to-read backlit LCD display, perfect for both bright and low-light conditions.
• Stable Positioning: Comes with a convenient fold-out tripod for stable, hands-free operation.

Ready When You Are: Your meter arrives prepared for immediate use, packaged in a protective soft carrying case, complete with 6 AA batteries, a comprehensive instruction manual, and an SD card to get you started right away.

Optional Power and Calibration: For extended use, power your device with the optional USB Power Cable #840058 or AC Adapter #840097. A N.I.S.T. traceable Certification Report is available for Relative Humidity and Air Temperature, ensuring calibration accuracy.
