Accurate environmental conditions, not from a distant weather station but from the palm of your hand with the Kestrel 5500 Handheld Pocket Weather Meter!

Wind speed, temperature, humidity, barometric pressure, wind direction and density altitude plus logging capabilities – the indispensable tool for portable environmental monitoring. The Kestrel 5500 measures every environmental condition plus wind direction, crosswind and headwind/tailwind. Use it golfing, sailing, flying, spraying, shooting and more. Drop-proof, dust-proof, waterproof and able to withstand extreme environments, your Kestrel weather meter travels with you anywhere you dare to go. The Kestrel 5500 has a larger, higher-resolution and contrast built-in dual color backlit display, made from extra-strong polycarbonate lens for improved font readability. Optional LiNK iOS and Android wireless connectivity and app support available. Like all Kestrel meters, the Kestrel 5500 is drop-proof, dust-proof, waterproof and able to withstand harsh environments without damage – so it can so it can work or play as hard as you do, wherever you do.

Kestrel 5500 with LiNK and iPadIn addition to measuring the current environmental conditions, the Kestrel 5500 tracks and logs over 10,000 sets of time-stamped data. Your data log can be transferred to a iOS/Android device wirelessly with the LiNK wireless communication option and the Kestrel LiNK app, or to a Windows PC or Mac with either the accessory Kestrel LiNK Dongle or waterproof USB Data Transfer Cable (Both sold separately).The true versatility of the Kestrel 5500 becomes apparent with the addition of the Kestrel Vane Mount. This precision-engineered accessory securely mounts the Kestrel 5500 to any tripod or other ¼-20 fitted bracket. Once mounted, the Kestrel 5500 becomes a full-featured weather station. Select "Add LiNK (Bluetooth Connectivity) + Vane Mount" or select the standard 5500 and purchase the vane mount separately in our Accessories section.

    Accuracy (+/-): Larger of 3% of reading, least significant digit or 20 ft/min
    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:

    • 0.5 °C
    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.

    Pressure

    Units of Measure: %
    Specification Range: 5 to 95% 25°C non-condensing
    Operational Range: 0 to 100% 
    Resolution: 0.1 %RH
    Accuracy (+/-): 3%RH
    Notes: 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.

    Compass

    Units of Measure:  Compass Heading in True or Magnetic
    Specification Range: 0 to 360°
    Operational Range: 0 to 360°
    Resolution: 1° 1/16th Cardinal Scale
    Accuracy: ±5°
    Notes: 2-axis solid-state magneto resistive 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.
