Kestrel 3500FW Pocket Fire Weather Meter

Rely on the Kestrel 3500FW Pocket Fire Weather Meter to rapidly and accurately assess meteorological conditions, including wet bulb and barometric readings.

When fighting wildfires, 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 (MPN# # 0835FWORA) Fire Weather Meter has been updated specifically for firefighting, 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.

Terry E.

Had this device about a week and just getting the hang of it. Can't wait to use it in Alaska next month.


A little Peace of mind for mom
My son is stationed in CA Desert. I wanted him to have a dependable lightweight piece of equipment that did not need blue tooth to work on his adventures and this has so far been very relialable and provided good information for hikes and exploring in extreme heat. I feel better knowing he has this light weight meter with him.
