Kestrel Fire Weather

Trusted, Accurate, and Connected Weather Monitoring for Firefighters

Every firefighter knows that wind, temperature and humidity drive fire behavior. Kestrel Weather Meters have been the trusted belt weather kit replacement for over 20 years. The 2016 Fire Line includes models with built-in calculation of Probability of Ignition (PIG) and Fine Dead Fuel Moisture (FDFM), features requested by wildland fire fighters.

Fighting Fires With Knowledge

As every firefighter knows, weather conditions are one of the most critical variables in fighting a fire. Wind speed and direction, temperature, and humidity are all measured frequently, tracked in detail, and entered into fire behavior models to inform decisions about deploying personnel, materials, and suppression tactics such as digging a fireline.

The Kestrel line now includes a full range of meters and loggers, including models with built-in Probability of Ignition (PIG) and Fine Dead Fuel Moisture (FDFM) readings. Wireless data transfer to smart phones and tablets using Kestrel LiNK™ makes communicating real-time conditions easier than ever. Heat stress prediction models help keep personnel safe from heat injury during training and operations.

For over two decades, wildland firefighters have relied upon Kestrel Weather Meters to provide accurate, fast and reliable measurement of weather conditions on location.

Taking Weather Observations

Every successful fire management strategy starts with accurate on-site weather observations. Kestrel Fire Weather Meters measure all relevant weather variables needed by Fire Behavior Analysts (FBAN’s), meteorologists, and deployed firefighters to understand how a fire is evolving and how to keep the crew safe. The new PRO line of Kestrel Fire Weather Meters give you the ability to track conditions and view trends right on the unit, as well as send detailed data reports using the free Kestrel LiNK app. The PRO meters also have the National Wildfire Coordinating Group (NWCG) Probability of Ignition (PIG) and Fine Dead Fuel Moisture (FDFM) tables built right in, eliminating the complexity, time and errors involved in employing paper lookup tables. Unlike a traditional belt weather kit, a Kestrel Meter is ready to take all readings instantly, and the PRO meters log temperature, humidity and pressure even when off, giving instant visibility of trends.

Kestrel Fire Weather Meters are ready to take measurements instantly, with no setup or lookup tables required. PRO meters have the FDFM and PIG tables built right in, and log temperature, humidity and pressure even while off.

Prescribed Burns

When managing a burn site, knowing environmental conditions are within prescription is important for compliance and to ensure that a fire doesn't get out of control. A Kestrel Fire Weather Meter provides wind speed, wind gust, average wind, temperature and humidity readings for monitoring conditions while burning. But, gathering sufficient weather data to make a decision on when to burn can require many time-consuming site visits prior to the burn. The new Kestrel DROP D3FW Fire Data loggers can be left on site to record days of round-the-clock temperature and humidity readings which can then be viewed on a mobile device and shared via email with the free Kestrel LiNK app – providing instant insight into the time of day with most conducive conditions. Although you do need to return to site to collect the data, you don’t even need to retrieve your DROP each time – the full data log is transmitted wirelessly as soon as you are within connection range (100' line of sight or more).

A Kestrel DROP D3FW is a great extension of the Kestrel line. Just leave it in place to log temperature and humidity round-the-clock and gain insight into the best time to conduct prescribed burns. Like all Kestrel Fire Meters, a Kestrel DROP is fully sealed and very tough.

Heat Stress Prevention

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 radiant heat of the sun, fire, or hot surfaces in the model. The Kestrel Fire Weather Meter PRO with 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.

By adding waterless WBGT readings to the full capabilities of the Kestrel Fire Weather Meter PRO, Kestrel has created the ultimate tool for protecting lives, houses, and property while ensuring safety for everyone involved.
