The next generation of environmental conditions monitoring is the here with the Kestrel 5000 Environmental Meter.

The Kestrel 5000 Environmental Meter is a remarkably powerful measuring and data logging tool, yet remarkably compact. The Kestrel 5000 provides the same trusted accuracy, reliability, and usability as the original Kestrel 4000.  Use it for research, safety, expeditions, agriculture and any other profession or activity where accurate on-the-spot conditions monitoring is key.   

The new Kestrel 5 Series platform adds many new features and options. If you’re familiar with the Kestrel 4500, the first thing you’ll notice is the larger, higher-resolution and contrast display and improved font readability. The Kestrel 5 series also includes a built-in dual color backlight, extra-strong polycarbonate lens and AA battery operation and offers optional LiNK iOS and Android wireless connectivity and app support.  Like all Kestrel meters, the Kestrel 5000 is drop-proof, dust-proof, waterproof and able to withstand harsh environments without damage – so it can travel with you anywhere you dare to go. A range of carry pouch options makes it even easier to take your Kestrel meter with you.

In addition to measuring the current environmental conditions, the Kestrel 5000 tracks and logs over 10,000 sets of time-stamped data. Your data log can be transferred to a mobile device wirelessly, or to a PC/MAC with either the optional Kestrel LiNK Dongle or waterproof USB Data Transfer Cable.

The true versatility of the Kestrel 5000 becomes apparent with the addition of the Kestrel Vane Mount. This precision-engineered accessory securely mounts the Kestrel 5000 to any tripod or other ¼-20 fitted bracket. Once mounted, the Kestrel 5500 becomes an independent 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 weather parameters. The Kestrel LiNK app (iOS and Android) also displays the Kestrel’s real-time readings on a vivid, customizable mobile device dashboard by providing a remote display that functions up to 100’ away (line of sight). The Kestrel 5000 meter can also be stored and carried in the Vane Mount belt pouch. The entire kit weighs just 10.5 ounces / 295 grams and is just 2.5 x 3 x 8.5 inches / 6.5 x 7.5 x 22 cm in size.

Kestrels have been put to the test in some of the harshest conditions on the planet. U.S. Special Forces, combat weather teams, wildland firefighters, smoke jumpers, Mt. Everest expeditions and auto pit crews are just a few who rely on a Kestrel to provide them with the crucial environmental data they need. Watch any on-screen meteorologist during a hurricane, and you’re sure to spot a Kestrel in action. Researchers have relied on Kestrel’s accuracy and portability for nearly 20 years, and you’ll find Kestrel referenced in many a peer-reviewed journal article. If environmental conditions are important in your profession or favorite activity, there is no better partner than a Kestrel 5000

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 (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 noncondensing 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.
