1 overview

1、Product Features

CFJD2、CFJD5The mechanical electronic anemometer (hereinafter referred to as the anemometer) adopts microprocessor technology and displays a 4-digit digital tube. The measured wind speed value or average wind speed value is directly displayed, with clear and bright display, and also has data storage function. Small in size, light in weight, easy to operate, and convenient to maintain, the anemometer adopts a thin film touch switch with good sealing performance, accurate and reliable.

2Main purpose and scope of use

The anemometer adopts advanced technologyIntelligent instruments designed with microprocessor chips are suitable for accurately measuring instantaneous wind speed and average wind speed at any time in coal mines with gas explosion hazards. They are also suitable for wind speed measurement in meteorological, transportation, construction, chemical, warehouse, and aerodynamic research applications.

3Environmental conditions for use
