Wildland firefighters train to withstand the challenge of heavy exertion in extreme conditions. Extreme heat is a constant companion, and protective gear exacerbates the physical strain on a firefighter’s body. Building heat acclimatization is a critical component of training, but doing so without incurring heat illness or injury is equally critical and challenging. Heat injury is a constant danger with many incidents of heat related illness occurring every year. Heat illness prevention programs recommend measuring Wet Bulb Globe Temperature (WBGT) and implementing ACGIH work/recovery and hydration guidelines. WBGT is a much more complete measure of heat stress for the firefighter because it includes the effects of the radiant heat of the sun, fire, or hot surfaces. The Kestrel Fire Weather Meter PRO WBGT adds the WBGT measurement to the full capability of the Fire Weather Meter Pro – making it the complete tool for monitoring WBGT and fire weather during training or operations. With pre-programmed ACGIH guidelines and alert settings to indicate when conditions have become extremely unsafe, the Kestrel Fire Weather Meter PRO with WBGT is the ultimate tool for increasing the safety of your crew.
Unlike other WBGT meters on the market, the Kestrel 5400 Fire Weather Pro WBGT is also a rugged, compact and easy-to-use portable weather station. Clip the Kestrel 5400 into the secure tripod vane mount to set up a weather and heat safety monitoring station in seconds. Measure wind speed, direction, temperature, humidity, pressure, dew point, elevation, density altitude, PIG, FDFM and more. In addition to measuring the current environmental conditions, the Kestrel 5400 Fire Weather Pro tracks and logs over 10,000 sets of time-stamped data. Your data log can be transferred to an iOS/Android device wirelessly with the LiNK wireless communication option and free Kestrel LiNK app, then exported and shared via email with ease. Data can also be transfered to a Windows/Mac device with either the accessory Kestrel LiNK Dongle or waterproof USB Data Transfer Cable (both sold separately).
The Kestrel 5400 Fire Weather Meter Pro WBGT offers a large, high-resolution and contrast display and easy font readability. It also includes a built-in dual color backlight, extra-strong polycarbonate lens and AA battery operation, along with LiNK iOS and Android wireless connectivity and app support. Like all Kestrel meters, the Kestrel 5400 Fire Weather Pro WBGT is drop-proof, dust-proof, waterproof and able to withstand harsh environments without damage – so it can so it can work as hard as you do.
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. There truly is no comparable environmental safety monitoring tool on the market. Adopt best safety practices for your team or workplace and add a Kestrel Heat Stress Tracker to your toolkit.

Yes! The Kestrel 5 Series now has both Android and iPhone integration through our Kestrel LiNK iOS and Android Apps. Kestrel LiNK iOS and Android apps allow LiNK enabled Kestrel 5 Series Meters and DROPs to connect wirelessly with mobile devices to view real-time measurements, receive on-screen alerts, download data and perform firmware updates. The Kestrel LiNK Ballistics app, designed specifically for the Kestrel 5700, Kestrel 5 series Sportsman, and Kestrel 5700 Elite meters, provides full gun management and access to the Applied Ballistics library of G1/G7 curves (5700) and custom drag models (Elite).

Make sure Bluetooth® is turned ON on your phone. On the Kestrel, go to the Main Menu->Bluetooth and turn it ON. Press the center button while Bluetooth is highlighted and check to ensure that Conct is set to PC/Mobile and it shows Available. Next go to the application that you are connecting with on your phone and select the Kestrel as the device you would like to connect with. Please note: if you do not find the Kestrel on your phone’s “standard” Bluetooth connection screen, that does not mean that the Kestrel is not working properly. Please first go to the application and try to connect through the application. The Kestrel should connect.
... PermalinkAll models of the Kestrel 5000 Series have optical data ports that can be seen through the openings of the battery door. A USB Data Transfer Cable can be purchased separately, which plugs directly into the back of the Kestrel and extends to a USB port in your computer. You will NOT be able to connect a non-LiNK model unit to a mobile device (e.g., any device without a USB port).
... PermalinkThese programs handle uploading the weather data from the Kestrel to a specific device. This weather data can then be exported into MS Excel. You can also update your firmware any of these programs. Visit the Kestrel LiNK Software and Apps page to learn more.
... PermalinkYou can now upgrade your Kestrel 5700 to the Elite version using the Kestrel LiNK Ballistics application. Simply connect your Kestrel to the iOS or Android version of the Kestrel LiNK Ballistics app. Select Upgrade in the top left corner. Enter you credit card information for the purchase and the upgrade should start after payment is completed. The upgrade will look similar to a firmware update.
... PermalinkAs can be seen in the pictures below, place your thumb on the bottom of the unit and slide the latch from the “Locked” to the “Unlocked” position. The battery door should pop up enough that you can remove it. If you have trouble opening the battery door, some slight pressure DOWN on the battery door itself with your other thumb may help release the latch.

First slide in the tab at towards the top of the unit, then gently press the bottom part of the battery door down until it snaps into place. Ensure that the O-ring remains in place on the battery door when closing.
... PermalinkNo. Since the Kestrel 5 Series meters utilize only one AA battery, there is no need to use the battery shim to separate two AAA batteries as in the previous version.
... PermalinkNK strongly recommends continual use of Lithium AA batteries in your Kestrel. Lithium batteries respond best in extreme temperatures and help prevent against any corrosion. Customers can also use Alkaline or Nickel Metal Hydride (NiMh) if they prefer, but we recommend turning “Auto Store” to “OFF” when placing these units in storage to minimize the drain on the battery. Also, please make sure you set the System->Battery setting to match the type of batteries that you are using.
... Permalink
No. Currently ONLY the Kestrel Sportsman Weather Meter with Applied Ballistics or the Kestrel 5700 Ballistics Weather Meter can be upgraded to the Kestrel 5700 Elite model.
... PermalinkAll of the Kestrel 5000 series units have the Night Vision option in addition to the standard white backlight. There is a menu selection that allows the customer to toggle between both options.
... PermalinkWind Speed – NK sells factory calibrated replacement impellers that can easily be installed by the customer. NK recommends replacing the impeller every 2-3 years depending on usage.
Humidity – The Kestrel 5 Series and DROP data loggers employ a highly accurate, calibrated, digital humidity sensor. Based on the sensor manufacturer's specifications and NK testing, drift on this sensor over time is minimal and field recalibration is likely to degrade accuracy rather than improve it. Factory calibration to validate and certify accuracy at a minimum of two RH points is available from NK. Kestrel 5000 series units can also be recalibrated in the field using our kit RH Recalibration Kit . During the five-year warranty period, NK will repair, recalibrate or replace any Kestrel 5 Series or DROP which drifts more than +/-1% RH/year since the date of manufacture.
Temperature – The thermistor in the Kestrel 5 series should not need to be recalibrated. If you think your sensor is incorrect, please contact techsupport@nkhome.com
Pressure – The pressure in the Kestrel 5 series should not need to be recalibrated. If you think your sensor is incorrect, please contact techsupport@nkhome.com
... PermalinkKestrel 5 series units with LiNK will need to use the Kestrel LiNK Wireless Dongle to connect with a computer. The Kestrel 5 series will not work with any internal Bluetooth modules. To connect, insert the Kestrel LiNK Dongle into an open USB port. On the Kestrel, go to the Main Menu->Bluetooth and turn it ON. Set Conct to "PC / Mobile." Open the application on the computer and select the Kestrel as the device to connect to. There is no more “pairing," "COM port numbers," or "PIN Codes" to worry about for those familiar with the 4000 series.
