GM8902, GM8902+ Air Flow Anemometer With LCD Display
This multifunction anemometer provides instant data for air speed, temperature, and air flow (CMM) on a triple-level LCD display with backlight. The tool features a wide measuring range of wind speed from 0–45 m/s (0–8800 ft/min), temperature from 0–45°C (32–113°F), and air flow (CMM) measuring range of 0–999900 m³/min, with USB interface for computer connectivity.
This weather device is ideal for windsurfing, sailing, and kite flying. It is also suitable for industrial and home applications such as measuring speed and temperature of CPU computer fans, air conditioners, and airflow over roofs or walls.
The all-in-one design enables efficient measurement in various fields including environmental protection, marine operations, aviation, industry, and agriculture with real-time output.
