Handheld Digital Anemometer Professional Multifunction Anemograph

This digital multifunctional anemometer is a professional instrument for measurement of wind speed, temperature, and humidity. It is designed for wind speed measurement in various environments, such as wind speed measurement engineering, quality control, and health control. It is applied in wind speed measurement for various occasions like factories, schools, offices, transportation routes, families, etc. Features: Six-wheel design for more accurately measure current wind speed, air volume, temperature and humidity. Wind speed/flow units and temperature units selection. Maximum/Minimum/Average wind speed measurement. 2.9-inch LCD screen with backlight for clearly reading. Real-time measurement when connecting USB with computer software. Automatic shutdown if there is no operation after 5 minutes. Data storage function, which can save up to 960 groups of measured data. Three-axis magnetic field sensor for wind direction angle measurement. Data hold function, low battery indication.
