The all-in-one hand-held belt weather kit replacement, including every critical weather measurement, PIG and FDFM.

Measure, log, track trends and expand capabilities with free Kestrel LiNK App.

The fast and easy tool for taking weather observations The Kestrel 5500 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 5500 Fire Weather Meter Pro offers a large, high-resolution and contrast display and highly readable numerals. The Kestrel 5500 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 5500 FWM 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. Data can also be downloaded to a PC with either the accessory Kestrel LiNK Dongle or waterproof USB Data Transfer Cable (Both sold separately).

    Notes: 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% @ 5º off-axis; -2% @ 10º; -3% @ 15º. Calibration drift < 1% after 100 hours use at 16 MPH | 7 m/s. Replacement impeller (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. *F/S only in Ballistics units. Beaufort not available in Ballistics units.

    Ambient Temperature

    Units of Measure: Fahrenheit, Celsius
    Specification Range:
    • -20.0 to 158.0 °F
    • -29.0 to 70.0 °C
    Operational Range:

    Notes: 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.
