Description

A low friction rotating vane anemometer and its rotation is sensed by an infrared light beam which add no friction. The resulting friction signal is processed by microprocessor assures maximum possible accuracy and provides special functions and features using RTC chip & memory having small package. A special 16 x 2 digit alphanumeric intelligent display is used for extra resolution and provides excellent viewing contrast in bright sunlight with back light. Suitable for most general measurements 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. Very simple and convenient to use one hand operation. Alphanumeric display with RTC clock with battery back up. 100 data with data-time store function. LP65 rating high impact ABS bodied for durability. Maximum & average functions. User selectable averaging time.
