Meter provides uncommon accuracy, sensitivity, and pocket-sized convenience. It is based on the principal that a freely turning turbine will rotate at a speed directly proportional to the wind speed.
To insure maximum sensitivity and accuracy, the turbine is suspended on sapphire jewel bearings, & its rotation is sensed by an infrared light beam which adds no friction.The resulting signal is processed electronically by LSI (Large Scale Integrated) circuit for improved reliability and< reduced size.
A special 3 digit display is used for extra resolution and provides excellent viewing contrast in bright sunlight. A handy switch selects between four different scales for unmatched versatility. Also, the totally enclosed turbine and compact size make it easy to carry, so you always have it when you need it.
