Product Description

The Kestrel 5100 offers a complete trackside weather station in your hand. Used widely by Go-Kart, Drag Racing, Formula 3 & 4 racers. It measures moisture content in grains, air density, relative air density, humidity and other critical factors. You can rely on it for the information you need to make perfect ET predictions and performance-maximising tuning and jetting decisions.

Current trackside conditions can be viewed over the large high-resolution screen that is clear and easy to read with built-in dual colour backlight. The screen is constructed from high-strength polycarbonate.

The Kestrel 5100 also calculates and logs over 10,000 sets of time-stamped data.

There are two versions of Kestrel 5100
STANDARD VERSION
With the standard Kestrel 5100 data can be transferred using the K5000 USB Data Transfer Cable (sold separately) to a Windows/Mac device. The free of charge Kestrel LiNK App will allow you to view and hold all data as well as download into .csv format.

LiNK VERSION
The Kestrel 5100 LiNK version has Bluetooth connectivity allowing you to transfer data wirelessly to an iOS (iPhone, iPad) device or Android smartphone or tablet when within range using the appropriate Kestrel LiNK App. You can also transfer data wirelessly to a Windows or Mac computer using the optional Kestrel Bluetooth USB Dongle (sold separately). Data can be viewed live on the App up to 100 feet away (line of sight).

When combined with the Kestrel Vane Mount and Kestrel Tripod the Kestrel 5100 becomes a stand-alone trackside monitoring station as the large wind vane and precision pivot keep the Kestrel oriented into the wind for continuous measurement and logging of all the key environmental parameters at the exact location required.

Mil-SPEC-810G drop tested with an IP67 waterproof rating the Kestrel 5100 is designed and constructed to withstand the harsh treatment it will receive trackside. The unit comes with a five-year warranty and certificate of conformity as standard.

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.
