The Extech 45168CP is a Mini Thermo-Anemometer which measures windspeed in ft/min, MPH, m/s, km/h, knots and in beaufort force with 10 second averaging function. Additional measurements include temperature, relative humidity, dew point, wet bulb, and windchill. The built-in compass provides wind direction and 360° readings, plus it has an easy-to-use calibration procedure for improved accuracy. Its water resistant housing floats and drop-tested to 1.8 m (6 ft). Featuring a replaceable, non-corrosive, plastic wind vane (impeller) and a tripod mount for hands free use. Complete with a CR2032 battery and a lanyard.
