The Kestrel 5400FW Fire Weather Meter offers all the same measurements and capabilities as the standard Kestrel 5400 Heat Stress Tracker, making it ideal for athletic, occupational, and heat safety monitoring
All this while also providing powerful additional tools specifically for wildland firefighting.
Just like the 5400, the 5400FW measures and reports temperature, humidity, wind speed, and WBGT (Wet Bulb Globe Temperature) for accurate heat stress and environmental monitoring in sports, military, and industrial settings.
In addition, the 5400FW includes advanced fire-weather features such as Fine Dead Fuel Moisture (FDFM) and Probability of Ignition (PIG) — critical indices used by wildland firefighters to evaluate ignition risk and fire behavior potential in the field. The 5400FW now includes Vapor Pressure Deficit (VPD). VPD quantifies the gap between the moisture currently in the air and the maximum moisture the air can hold at saturation. This measurement reveals the atmosphere’s drying potential—one of the most important drivers of fuel moisture (FM). Because FM is fundamental to wildfire behavior and management, being able to estimate it accurately in the field—without relying on time-consuming laboratory analysis—marks a major operational advancement.
In short, the Kestrel 5400FW does everything the 5400 does — and more. It’s the perfect choice for anyone who needs reliable heat stress tracking and the added capability to assess fire weather conditions.
