Kestrel 5400FW Fire Weather Meter Pro WBGT with LiNK, Compass and Vane Mount

The Kestrel 5400FW WBGT Fire Weather Meter Pro is the ultimate tool for monitoring heat stress and fire weather conditions on the fire ground. Trusted by firefighters and professionals across Australia, this all-in-one portable weather station offers more than just standard weather measurements—it provides comprehensive fire weather data and advanced heat stress monitoring with WBGT (Wet Bulb Globe Temperature), ensuring safety during high-risk fire ground operations and training exercises.

What Sets the Kestrel 5400FW Apart?

The Kestrel 5400FW is an upgrade from the Kestrel 5400 Heat Stress Meter and earlier models like the Kestrel 3000 and Kestrel 3500FW. It includes unique features such as the PIG (Probability of Ignition) Screen and FDFM (Fine Dead Fuel Moisture) Screen, making it indispensable for fire professionals. With no need for recalibration, this unit stays accurate within calibration drift for up to 5 years, ensuring reliable performance every time.

Top Features of the Kestrel 5400FW WBGT Fire Weather Meter Pro

• Comprehensive Heat Stress Monitoring: Measure and log Wet Bulb Globe Temperature (WBGT), Thermal Work Limit (TWL), and other vital environmental metrics.
• Waterless, Lightweight, and Easy to Use: The unit’s waterless sensors ensure low maintenance, while its compact size makes it easy to carry in the field.
• LiNK Bluetooth® Connectivity: Seamlessly send real-time weather data and heat stress alerts to your mobile device using the Kestrel LiNK app. It is compatible with iPhones, iPads, Android, and tablets, ensuring you stay connected in the most challenging conditions.
• PIG and FDFM Readings: Specialised screens for Probability of Ignition and Fine Dead Fuel Moisture, critical for firefighting and bushfire management in Australia's harsh environment.
• Durability and Precision: Waterproof, shock-resistant (meets MIL-STD-810F 516.5), and designed to withstand extreme conditions. Perfect for firefighting, mining, agriculture, and other outdoor operations.

Advanced Weather Monitoring for Fire Professionals

The Kestrel 5400FW doesn’t just measure temperature and humidity; it calculates natural wet bulb temperature, globe temperature, wind speed, barometric pressure, relative humidity, and more. With on-screen alarms for heat stress conditions, you can quickly act when temperatures enter danger zones, ensuring safety on the fire ground.

Why Choose WBGT Over Heat Index?

Unlike the standard Heat Index, which only considers temperature and humidity in shaded areas, the WBGT considers sun exposure, wind speed, humidity, and solar radiation. It’s the most accurate way to assess heat stress in direct sunlight, making it the preferred method for fire, military, and sports professionals worldwide.

Effortless Data Logging and Sharing

With LiNK Bluetooth® wireless technology, all data can be recorded and shared via Kestrel LiNK for iOS and Android or exported to Windows and Mac computers. Quickly generate and send detailed weather reports to keep your team informed and safe, no matter where you are.
