The relationship between wind speed and wind level
Level 1: 0.3-1.5m/s Slight movement of leaves, soft wind
Level 2: 0.3-1.5m/s. There is a slight noise when the leaves move, and the wind is soft
Level 3: 3.4-5.4m/s Small branches sway incessantly, with a gentle breeze
Level 4: 5.5-7.9m/s small branch shaking, gentle wind
Level 5: 8.0-10.7m/s shaking of large branches, clear and strong wind
Level 6: 10.8-13.8m/s whole tree shaking, strong wind
Level 7: 13.9-17.1m/s Small branches broken, strong wind
Level 8: Large branches break at a speed of 17.2-20.7m/s, strong winds
Level 9: A small tree is blown down at a speed of 20.8-24.4m/s due to strong winds
Level 10: Trees with a bowl mouth thickness of 24.5-28.4m/s are blown down by strong winds
11-12 levels: Trees larger than 28.4m/s are blown down or uprooted, causing a storm or hurricane

The DT-82 mini anemometer can be widely used for measuring the wind speed of fans, air conditioners, exhaust fans, etc. in homes/offices/cars. It is precise and durable, bringing you the best living experience.
