Designed to provide fast and accurate measurement of the critical weather conditions impacting the behavior of wildland fires.
Kestrel Fire Weather Meters empower firefighters with the real-time and trend data to make critical decisions in their mission to protect lives, houses, and property while ensuring safety for everyone involved.
All Kestrel Fire Weather Meters provide wind speed, relative humidity, temperature, psychrometric wet bulb temperature, altitude, pressure trends, barometric pressure, dew point temperatures, heat stress index and wind chill environmental measurements. The enhanced Pro Series has a digital compass for wind direction, preloaded tables for Probability of Ignition (PIG) and Fine Dead Fuel Moisture (FDFM) as well as on-screen graphing history. Pro series with optional LiNK wireless connectivity sends current and logged weather and heat data to mobile devices keeping crews informed, prepared and most of all, safe. Also, see the Kestrel 3000. The Kestrel 3000 has been and is another popular choice with wildland firefighters. While not part of the Fire Weather Meter line, the 3000 reports wind speed, humidity, temperature, dew point, wind chill and heat stress index.

Overview:
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.

Kestrel DROP D3FW Fire Weather Monitor
MPN# 0730FWORA
Regular price $129.00 USDTrack weather conditions and record trends at a burn site or from the minute you get on a fire, then export data to get crucial information where it needs to go.
Kestrel DROP D3FW Fire Weather Monitor Overview
When managing a burn site, knowing environmental conditions are within prescription is important for compliance and to ensure a fire doesn’t get out of control. Gathering sufficient weather data from site visits to make a decision on when to burn can be challenging. In addition to the full wind and weather readings from a Kestrel weather meter, the new Kestrel DROP data loggers can be left on site recording a history of conditions and trends which can then be viewed on a mobile device when within range via Bluetooth and shared via email.
Small, Accurate, Rugged and Waterproof
Each Kestrel Fire Weather DROP measures just 1 x 1.8 x 2.4 inches (24 x 46 mm x 60 mm) and weighs just 1.2 ounces (34 grams). DROP loggers meet military and international standards for water, dust and shock resistance (IP-67 and MIL-STD-810G) and are conveniently equipped with a sturdy D-ring for hanging wherever needed.
Log, View and Share on the Kestrel LiNK App
Kestrel LiNK is the free app that powers the Fire Weather DROP data logger. With Kestrel LiNK on your smart phone or tablet, you can view real-time readings from any DROP logger within wireless range (up to 100’ or more line of sight) via Bluetooth® low energy. Min/Max/Average readings are clearly displayed and the data log is viewable as a scrolling graph with detailed data for each logged point. The Kestrel LiNK app also allows adjustment of the logging interval and other settings as well as real-time threshold alerts. Readings can be updated as frequently as every 2 seconds and logging time and date are automatically updated whenever connected to your smart device. You can also send and share real-time and logged environmental data via email, Facebook or Twitter
