When fighting urban and wild fires and protecting lives and property while ensuring safety for everyone involved demands accurate fire behaviour predictions based upon quality environmental data. 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 the firefighting market, adding barometric pressure, altitude and wet bulb readings with an easy-to-read Probability of Ignition (PIG) and Fine Dead Fuel Moisture (FDFM) reference card that comes with every unit. This single handheld instrument replaces all the items included in your Belt Weather Kit, providing consistently accurate measurements without prepping a sling psychrometer or risking the possibility of human error.

Mil-SPEC-810G drop tested with an IP67 waterproof rating the Kestrel 3500FW is designed and constructed to withstand the harsh working environment it will encounter. The unit comes with a five-year warranty and certificate of conformity as standard.
