Product Description 

 The SLF-S wind cup anemometer three cups anemometer portable design instruments to measure parts of a monolithic technology can simultaneously measure the instantaneous wind speed, average wind speed, the instantaneous wind level, the five parameters of the average wind level and the corresponding wave height . The instrument used in liquid crystal display as a professional custom, domestic original measurement parameters and measurement units directly with Chinese characters displayed on the LCD screen, digital display of measured data up to 18mm more remote viewing, to facilitate the teaching demonstration. 

 Performance characteristics of 
 The SLF-S wind cup anemometer with low-power design and use of liquid crystal (LCD) display, greatly reducing the power consumption of the instrument. With data latch function and ease of reading, in the wind part of the Auto North device without manual measurements on the north, to simplify the measurement operation. The instrument has a small size, light weight, full-featured, low power consumption, large characters, display intuitive, easy to carry, etc., can be widely used for areas such as agriculture, forestry, environment, marine scientific expedition to measure atmospheric wind parameters.
