The Air Flow Meter 45168CP is a Mini Thermo-Anemometer that measures windspeed in feet per minute, MPH, meters per second, kilometers per hour, knots, and beaufort force with a 10-second averaging feature. Temperature, relative humidity, dew point, wet bulb, and windchill are some more metrics. The built-in compass provides wind direction and 360° readings, as well as a simple calibration technique for increased accuracy. Its water-resistant enclosure floats and is drop-tested to 1.8 metres (6 feet). Includes a replacement, non-corrosive plastic wind vane (impeller) and a tripod mount for hands-free operation. Comes with a CR2032 battery and lanyard.
