A low friction rotating vane anemometer and its rotation is sensed by an infrared light beam which adds no friction. The resulting signal is processed by microprocessor assures maximum possible accuracy and provides special functions and features using RTC chip & Memory having small package. A special 16X2 digit Alphanumeric intelligent display is used for extra resolution and provides excellent viewing contrast in bright sunlight with back light. Suitable for most generameasurements in heating, ventilating and air conditioning applications. Direct reading of air velocity-no separate timer required. Supplied in carrying case. Powered by 9V PP3 battery. Direct reading in meter/second.
