Product Overview

The fast and easy tool for taking weather observations, the Kestrel 5500FW Fire Weather Meter Pro provides NIST-traceable accuracy, reliability and usability when it matters most. Measure every environmental condition plus PIG and FDFM and view trends with on-screen data graphing. Drop-proof, dust-proof, waterproof and able to withstand extreme environments without damage, your Kestrel Fire Weather meter can stand up to the abuses of work on a fire line wherever you're assigned. A variety of carry pouch options makes it even easier to take your Kestrel Fire Weather meter with you.

The Kestrel 5500FW Fire Weather Meter Pro offers a large, high-resolution and contrast display and highly readable numerals. The Kestrel 5500FW also includes a built-in dual color backlight, extra-strong polycarbonate lens and single AA battery operation. In addition to measuring the current environmental conditions, the Kestrel 5500F tracks and logs over 10,000 sets of time-stamped data, providing a complete history of conditions on the fire from the moment you arrive. With optional LiNK wireless connectivity, your data log can be transferred to a Kestrel LiNK app (available on Android) for easy export and email to an FBAN or meteorologist. LiNK enabled units come with Kestrel Vane Mount, creating a wireless pop up weather station for accurate readings and tracking trends.

Data can be downloaded to a PC with either the accessory Kestrel LiNK Dongle or waterproof USB Data Transfer Cable (Both sold separately).

1 inch|25 mm diameter impeller with precision axle and low-friction Zytel® bearings. Startup speed stated as lower limit, readings may be taken down to 0.4 m/s | 79 ft/min| 1.5 km/h | .9 mph | .8 kt after impeller startup. Off-axis accuracy -1% @ 5° off-axis; -2% @ 10°; -3% @ 15°. Calibration drift < 1% after 100 hours use at 16 MPH | 7 m/s. Replacement impeller (NK PN-0801) field installs without tools (US Patent 5,783,753). Wind speed calibration and testing should be done with triangle on impeller located at the top front face of the Kestrel. Measuring wind speeds above 60 m/s / 134.2 mph can damage the impeller.

Airflow of 2.2 mph|1 m/s or greater provides fastest response and reduction of insolation effect. For greatest accuracy, avoid direct sunlight on the temperature sensor and prolonged sunlight exposure to the unit in low airflow conditions. Calibration drift is negligible for the life of the product. For further details, see Display & Battery Operational Temperature Limits
Relative Humidity ±2%RH 0.1 %RH 10 to 90% 25°C non-condensing To achieve stated accuracy, unit must be permitted to equilibrate to external temperature when exposed to large, rapid temperature changes and be kept out of direct sunlight. Calibration drift is typically less than ±0.25% per year.

Monolithic silicon piezoresistive pressure sensor with second-order temperature correction. Between 1100–1200 mbar, unit will operate with reduced accuracy. Sensor may not operate above 1200 mbar and can be damaged above 6,000 mbar or below 10 mbar. Calibration drift is negligible for the life of the product.
Compass ±5°
1/16th Cardinal Scale
0 to 360° 2-axis solid-state magnetoresistive sensor mounted perpendicular to unit plane. Accuracy of sensor dependent upon unit's vertical position. Self-calibration routine eliminates magnetic error from batteries or unit and must be run after every full power-down (battery removal or change). Readout indicates direction to which the back of the unit is pointed when held in a vertical orientation. Declination/variation adjustable for True North readout.
