Features:

  • The Ambient Weather WM-4 is a comprehensive handheld weather station, directional compass, heat index monitor and psychrometer, all in one compact, portable, rugged package.
  • The WM-4 measures wind speed, wind direction, temperature, relative humidity and compass direction, and calculates wind gust, dew point, wet bulb and dry bulb temperature, Delta T, wind chill and heat index.
  • It has a USA-made fluxgate compass for precise digital wind direction measurement, and it can also be used to calculate crosswind & head/tail wind readings with the built in wind vane.
  • The jack knife case design protects the unit, and allows you to hold the case while taking precise temperature measurements, avoiding false readings from your hand temperature.
