Kestrel 5200 Description
The Kestrel 5200 covers a 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.
Construction
The Kestrel 5200 carries built-in evaporation rate calculations and displays the result direct to screen with no human calculation or interpretation errors. This data enables effective decisions regarding addition of additives to the mix or curing adjustments, preventing costly plastic shrinkage cracks. The integral anemometer allows you to monitor and log on-site wind speeds ensuring safe operation of cranes. The heat index calculations can be utilised to advise on safe working conditions, rest periods and rehydration volumes.
HVAC
Volume air flow calculations are made incredibly simple just input the duct shape and dimensions and move the Kestrel 5200 across the duct. You’ll get immediate and average volume air flow without the need for any geometry or calculations. Readings that greatly assist in commissioning and servicing HVAC systems. In addition, the Kestrel 5200 also measures moisture content in the air, useful when specifying dehumidification requirements.
Agriculture
The Delta T functionality measures the spread between the wet bulb temperature and the dry bulb temperature (in degrees C). This offers a quick guide to determining acceptable spraying conditions. For example, it is not recommended to apply pesticides when Delta T is above 10 – a range of 2 to 8 is ideal. With the Kestrel 5200, the calculation is done for you, accurately and simply.
The Kestrel 5200 also calculates and logs over 10,000 sets of time-stamped data.
There are two versions of Kestrel 5200:
• With the standard Kestrel 5200 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 5200 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 5200 becomes a stand-alone environmental 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 5200 is designed and constructed to withstand the harsh treatment it will receive from construction sites, farms or HVAC engineers. The unit comes with a five-year warranty and certificate of conformity as standard.

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. |
