Kestrel 5000 Advanced Environmental Meter
Kestrel 5000 Advanced Environmental Meter
The Kestrel 5000 Environmental Meter is a remarkably compact yet powerful measuring and data logging tool. Use it for research, safety, expeditions, agriculture and any other profession or activity where accurate on-the-spot conditions monitoring is key.
Current weather 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 5000 also calculates and logs over 10,000 sets of time-stamped data.
There are two versions of Kestrel 5000 …
• With the standard Kestrel 5000 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.
• The Kestrel 5000 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 5000 becomes a stand-alone monitoring station as the large wind vane and precision pivot keep the Kestrel oriented into the wind for continuous measurement and logging of wind speed and all other key environmental parameters.
Mil-SPEC-810G drop tested with an IP67 waterproof rating the Kestrel 5000 is designed and constructed to withstand the harsh working environment it will encounter. The unit comes with a five-year warranty and certificate of conformity as standard.

| Wind Speed | Air Flow | Larger of 3% of reading, least significant digit or 20 ft/min | 0.1 m/s 1 ft/min 0.1 km/h 0.1 mph 0.1 knots 1 B* 0.1 F/S* |
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* |
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. *F/S only in Ballistics units. Beaufort not available in Ballistics units. |

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. |
| Pressure | ±1.5 mbar at 25°C, 700-1100 mbar/ ±0.044inHg at 77°F 20.67-32.48 inHg/ ±0.022 PSI 10.15-15.95 PS |

25°C/77°F, 700-1100 mbar/20.67-32.48 inHg/10.15-15.95 PSI |
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. |
