Description
Specifications

Whether you're pouring concrete, balancing HVAC systems, or spraying crops, take the calculations and guess-work out of your job with integrated specialty calculations

No more guessing or using inaccurate data from miles away.

The next generation of professional environmental monitoring is the here with the Kestrel 5200 Weather Meter.

The Kestrel 5200 provides the same trusted accuracy, reliability, and usability as the original Kestrel 4200 and 4300. With its complete suite of environmental measurements plus special features designed to aid HVAC technicians, construction and agriculture professionals, the Kestrel 5200 outperforms the competition as the most compact and complete environmental meter and data logger for all professional uses.

The new Kestrel 5 Series platform adds many new features and options. If you’re familiar with the Kestrel 4200 or 4300, 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 5200 is drop-proof, dust-proof, waterproof and able to withstand harsh environments without damage – so it can work as hard as you do, wherever you do. A range of carry pouch options makes it even easier to take your Kestrel meter with you.

The Kestrel 5200 offers advanced calculators and readings that are unique in the portable meter market and are designed to make your job easier. In addition to measuring current environmental conditions, the Kestrel 5200 tracks and logs over 10,000 sets of time-stamped data. Your data log can be transferred to a mobile device wirelessly with the LiNK wireless communication option and Kestrel LiNK app, or to a PC/MAC with either the accessory Kestrel LiNK Dongle or waterproof USB Data Transfer Cable (available separately).

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 the Weather Channel during a hurricane, and you’re sure to spot a Kestrel in action. Technicians have been purchasing Kestrel meters for their toolboxes for years, knowing they will provide the readings they need immediately and reliably. Construction managers all over the world have relied on their Kestrel meters to ensure work-site safety and cost-effective concrete pours. Farmers that need know a Kestrel meter can help them avoid property damage and maximize productivity. Shouldn’t YOU be working with Kestrel?

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
Ambient Temperature	0.9 °F 0.5 °C	0.1 °F 0.1 °C	-20.0 to 158.0 °F -29.0 to 70.0 °C	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.

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.
Compass	5°	1° 1/16th Cardinal Scale	0 to 360°	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.

Display & Backlight	Multifunction, multidigit monochrome dot-matrix display. Choice of white or red LED backlight.
Response Time & Display Update	Display updates every 1 second. After exposure to large environmental changes, all sensors require an equilibration period to reach stated accuracy. Measurements employing RH may require longer periods particularly after prolonged exposure to very high or very low humidity. WBGT requires about 8 minutes to reach 95% accuracy and about 15 minutes to reach 99% accuracy after exposure to large environmental changes.
Data Storage & Graphical display Min/Max/Avg History	Logged history stored and displayed for every measured value. Manual and auto data storage. Min/Max/Avg history may be reset independently.
