The WeatherHawk WM-350 hand held wind meter is a comprehensive weather monitor that measures a full range of environmental data specific to your location. It includes a 48-hr visually displayed bar graph for every function, hour-by-hour. The USA-made fluxgate compass reads when held vertically, gives wind direction in degrees and compass points; and it calculates crosswind, head/tail wind. The compass can be calibrated for variation, declination and deviation. In addition to wind speed and direction, temperature, barometric pressure, altitude, and humidity, the unit includes Wind Chill, Wet Bulb, Dew Point, Delta T and Density Altitude. WM-350 provides an audible storm alarm that alerts you to weather changes, even if the unit is off. The unit includes the AccuWeather Comfort Index and it can be adjusted based on sun intensity to provide a superior human based “feel” for Heat Index. WM-350 can be tripod-mounted and accommodates the Model SM-WT wind tunnel accessory for very precise wind measurements. All WindMates are designed with a wind speed accuracy of better than +/- 3%.
