Designed for wildland firefighting applications, the rugged 3500FW provides a variety of weather measurements and also includes an easy-to-read Probability of Ignition (PIG) and Fine Dead Fuel Moisture (FDFM) reference card. The meter measures barometric pressure, pressure trend, altitude, temperature, relative humidity, wind speed, wind chill, dew point temperature, wet bulb temperature (psychrometric), and heat stress index. The 3500FW features a large backlit display, a real-time clock, and a hold function.
