The Extech 45118 is a compact instrument that measure airspeed and temperature with windchill. The unit is waterproof and has a convienent fold-up housing to protect it when not in use. A tripod mount is also built-in for prolonged test situations.
Windspeed
- Measures ft/min, MPH, m/s, km/h, Knots and Beaufort Force
- Selectable averaging function of 5, 10, or 13 second intervals
- Replaceable non-corrosive plastic wind vane (impeller)
