R.M. Young’s 05103-45 Alpine Wind Monitor is for customers who need an ice-resistant wind speed and direction sensor. This rugged instrument, available now from Campbell Scientific, is designed to make accurate measurements in harsh, alpine conditions. Design features include a black exterior—for better melt off—covered with an ice-resistant coating. The 05103-45 also has a smaller propeller diameter than the other wind monitor models, which minimizes vibration at high wind speeds.
