US Manufacturing

The entire Kestrel line is designed and built in the USA. No other handheld weather meter is. Some electronic components have to be sourced overseas these days, but Kestrel buys American wherever possible. Kestrel believes US manufacturing is the only way to ensure that every Kestrel will do its job right. Kestrel believes it’s important to do its part to keep manufacturing alive and well in the US.

Sensor Specifications

Wind Speed
Units of Measure:	mph \| kt \| B \| m/s \| ft/min / km/h
Specification Range:	0.6 to 40.0 m/s 118 to 7,874 ft/min 2.2 to 144.0 km/h 1.3 to 89.5 mph 1.2 to 77.8 knots 0 to 12 B* 2-131.2 F/S*
Operational Range:	0.6 to 60.0 m/s 118 to 11,811 ft/min 2.2 to 216.0 km/h 1.3 to 134.2 mph 1.2 to 116.6 knots 0 to 12 B* 2-196.9 F/S*
Resolution:	0.1 m/s 1 ft/min 0.1 km/h 0.1 mph 0.1 knots 1 B
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:	14.0.0 to 131.0 °F -10.0 to 55.0 °C
Resolution:	0.1 °F 0.1 °C
Accuracy (+/-):	0.9 °F 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:	inHg, hPA, mb
Specification Range:	25°C/ 77°F 750-1100 hPa\|mbar 22.15-32.48 inHg 10.88-15.95 PS
Operational Range:	0.30 to 48.87 inHg 10.0 to 1654.7 hPa\|mbar 0.14 to 24.00 PSI 14.0 to 131.0 °F -10.0 to 55.0 °C
Resolution:	0.1 hPa\|mbar 0.01 inHg 0.01 PSI
Accuracy (+/-):	1.5 hPa\|mbar 0.044 inHg 0.022 PSI
Notes:	Monolithic silicon piezo-resistive pressure sensor with second-order temperature correction. Between 1100–1600 mbar, unit will operate with reduced accuracy. Sensor may not operate above 1600 mbar and can be damaged above 6,000 mbar or below 10 mbar. Calibration drift is negligible for the life of the product.
Relative Humidity
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.

Kestrel 5500 Manual and Complete Sensor Specifications

Description

Gain precise details on environmental factors with the Kestrel 5500 Handheld Pocket Weather Meter, allowing you to easily measure data from your own location.

The Kestrel 5500 is the ultimate tool for portable environmental monitoring, providing readings on virtually every environmental factor such as wind speed, temperature, humidity, barometric pressure, wind direction, and density altitude. Additionally, the Kestrel 5500 allows for logging and data storage. The Kestrel 5500 is the perfect companion for golfing, sailing, flying, spraying, and shooting, and its superior durability ensures it can handle the toughest weather and terrain. The built-in dual color backlit display has been strengthened with an extra-strong polycarbonate lens for improved font readability, while optional LiNK iOS and Android wireless connectivity and app support opens up further possibilities.

In 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.

Excellent field weather meter. Very accurate and easy to handle.
The only minus (for which I took one star off) is a very short Bluetooth range - if I move more than 2m with the phone from the meter, it gets disconnected. BT is supposed to have around 10m range.
