When fighting wild fires, protecting lives, houses, and property while ensuring safety for everyone involved demands accurate fire behavior predictions based upon good weather observations. Kestrel weather meters have been relied upon by fire fighters for decades to provide fast, accurate measurement of wind speed, temperature and humidity. The Kestrel 3500 Fire Weather Meter has been updated specifically for fire fighting, adding barometric pressure, altitude and wet bulb readings and an easy-to-read Probability of Ignition (PIG) and Fine Dead Fuel Moisture (FDFM) reference card – everything required for a complete weather observation. This one rugged, handheld instrument easily replaces all of the items included in your Belt Weather Kit, providing consistently accurate measurements without prepping a sling psychrometer or risking the possibility of human error.
IP67 waterproof and Mil-SPEC-810G drop tested, Kestrels are built for the abuse that work on a fire line can dish out. The Kestrel 3500 Fire Weather Meter includes a hard, rubberized slip-on cover that protects the display and impeller, even when tossed in your pack. Kestrel Weather & Environmental Meters are designed & manufactured in the U.S.A and are backed by our 5-year warranty. Each Kestrel 3500 is factory calibrated and comes with a certificate of conformity and may be factory or field recalibrated.
This meter measures: Altitude, Barometric Pressure, Dew Point, Heat Stress Index, Pressure Trend, Relative Humidity, Temperature, Wet Bulb Temperature (Psychrometer), Wind Chill and Wind Speed.

Weather has a very impactful effect on both starting and sustaining fires. Wind, temperature and humidity are all important factors to take into consideration. The Kestrel Weather Meter 2016 Fire Line includes lifesaving and important features such as Probability of Ignition (PIG) and Fine Dead Fuel Moisture (FDFM) which saves time and ensures consistency of readings between emergency professionals.
Fire fighters need accurate, timely and current situational awareness in order to respond effectively to any fire hazard they face. Weather conditions are unpredictable and can cause a bad situation to get worse if you are not tracking the latest conditions. Wind speed and direction, temperature and humidity are factors fire fighters take into consideration especially when digging firelines.
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 when working in extreme hot weather conditions.

High and low wind speeds, temperature, humidity and altitude are all important factors to take into consideration when faced with a wild fire. It is important to know the surrounding conditions to understand how a fire is evolving. The new PRO line of Kestrel Fire Weather Meters measures these variables and allows you to communicate with your team detailed data reports using the free Kestrel LINK app. Eliminate errors with these meters by having the National Wildfire Coordinating Group (NWCG) Probability of Ignition (PIG) and Fine Dead Fuel Moisture (FDFM) tables built right in. The PRO models even data log all your readings so you have immediate trend information at your fingertips.
Learn MoreControlled or prescribed burning is an important technique used in forest management and farming to reduce fuel buildup and decrease the likelihood of serious hotter fires. Since future weather is uncertain it’s important to gather all the necessary readings you can to monitor while conducting these burns. Wind speed, wind gust, average wind, temperature and humidity are all measurements you can take with the new Kestrel DROP D3FW Fire Data loggers. These meters can be left on site to record days of round-the-clock temperature and humidity readings and then can be viewed on a mobile device. This allows you to gather adequate weather information on the day before and the day of a burn. Fuel will not burn when wet and will not burn adequately when relative humidity is too high. Fire control becomes difficult when relative humidity is too low. Now you can take the guess work out of these important factors and manage the burn site to ensure that a fire does not get out of control.

During the hot summer, risks of heat stress increase exponentially for wildland firefighters when working in extreme conditions. Fire fighters must take into consideration the added impact of wearing heavy Personal Protective Equipment (PPE) on heat stress. Temperature is not the sole indicator of heat stress. You must take into consideration the heat stress in direct sunlight which takes into account temperature, humidity, wind speed, sun angle and cloud cover to give you a reading of how hot it really feels. The Kestrel Fire Weather Meter PRO with WBGT is an all-inclusive weather station with a heat stress indicator to keep fire fighters and emergency personnel safe when working outside. This meter has pre-programmed ACGIH guidelines and alert settings to indicate when conditions have become extremely unsafe which makes it the ultimate tool for safety of your team.
