Kestrel 5500FW Fire Weather Meter Pro

DESCRIPTION

The 5500FW provides critical environmental data for wildland firefighters and offers built-in calculation of Probability of Ignition (PIG) and Fine Dead Fuel Moisture (FDFM) with no reference tables needed! This versatile meter also measures wind speed, direction (wind direction and orientation), relative humidity, temperature, wet bulb temperature (psychrometric), altitude, density altitude, barometric pressure, crosswind/headwind/tailwind, heat stress index, dew point temperature, station pressure (absolute pressure), and wind chill. The meter tracks and logs over 10,000 sets of time-stamped data. On-screen graphing of history allows for the observation of environmental trends and more intuitive prediction of fire behavior. Additional features include a compass and a large, hi-res, hi-contrast, graphic display that is easily readable in bright sunlight and is also backlit for nighttime use. The rugged 5500FW is waterproof to IP67 standards, floats, and is drop tested to MIL-STD-810G standards. The meter can be used as a hand-held device or mounted on a tripod (sold separately) using a vane mount. Lanyard, protective pouch, lithium AA battery (average life 400 hours), certificate of conformity, and instruction manual are included. Five-year manufacturers warranty.
