Digital Anemometer Air Velocity Air Volume Wind Speed Meter Thermometer GM8901 GM8901+ GM8909
Product Overview
This multifunction anemometer provides instant data such as air speed and temperature on a dual-level LCD display with backlight. With a wide measuring range of wind speed from 0 to 45m/s (0 to 8800ft/min) and temperature from 0 to 45°C (32 to 113°F), this professional instrument delivers precise environmental measurements.
Ideal for windsurfing, sailing, and kite flying enthusiasts, this device also serves industrial and home applications including measuring CPU computer fan speeds, air conditioner performance, and airflow analysis over roofs or walls.
