Kestrel Fire Weather Meter 3500FW Safety Orange — Waterproof IP67, Backlit Display

Designed and manufactured in the USA, the 3500FW combines wind, temperature, humidity and specialized fire metrics into one durable package. Its safety-orange housing, large backlit display and IP67-rated waterproofing make it easy to find and use in smoky, wet, or rugged environments. The meter delivers built-in calculations such as PID (Potential Ignition Distance) and FDFM (Fire Danger Fuel Model) alongside standard parameters, so teams can collect consistent, field-ready data without manual interpolation.

What specific measurements does the 3500FW provide?

The Kestrel 3500FW reports core atmospheric and fire-related parameters with built-in computation for common operational needs. It captures temperature, relative humidity, wet bulb temperature, wind speed, and calculates heat stress indexes and fire-oriented diagnostics.

• Air temperature and relative humidity for baseline environment readings
• Wet bulb temperature and heat stress indices to assess physiological risk
• Wind speed measurements tailored for fire behavior observation
• PID and FDFM outputs to support fire danger and spread considerations

How is the 3500FW built to withstand firefighting and field operations?

Durability and usability were prioritized: the meter meets MIL-STD-810F drop testing and is waterproof to IP67 standards, so it survives drops, immersion and rough handling. The unit floats if dropped in water and its large backlit screen is readable in low light and smoky environments.

• Rugged, USA-made construction with impact-resistant housing
• IP67 waterproofing for immersion and heavy rain use
• Drop-tested to military standards for field survivability
• High-contrast, backlit display for visibility in smoke or darkness

How does the 3500FW save time and reduce error during incident assessments?

By integrating standardized computations directly into the device, the meter eliminates the need for separate charts or manual math, producing consistent, repeatable results at the point of use. Fast, accurate readouts allow teams to make informed decisions quicker and reduce transcription or calculation mistakes during high-pressure operations.

• Onboard algorithms deliver immediate PID and FDFM outputs
• One-person operation with immediate, formatted readings
• Large numeric display and intuitive interface cut data-collection time
• Eliminates manual lookups and reduces transcription errors

What accessories and practical considerations should users know?

The meter’s compact footprint fits in pockets or gear pouches and works with common mounting or lanyard options for hands-free carry. Battery life and care instructions are straightforward; keeping sensors clean and following calibration recommendations preserves accuracy over time.

• Compact size with lanyard or mounting compatibility
• Replaceable battery design for field swap-outs
• User-replaceable sensor covers and recommended cleaning regimen
• Follow periodic calibration schedules for peak measurement fidelity

Who is this for: The Kestrel 3500FW is intended for wildland and structural fire crews, incident commanders, HAZMAT teams, search-and-rescue units, and military operators who need rugged, quick, and fire-specific environmental data. It’s also a solid tool for land managers and professional safety teams who require dependable field measurements and embedded fire-behavior metrics without bulky equipment or complex workflows.
