Feature: 1. 3 Cup Wind Sensing: This wind speed detector uses 3 fan blades for wind speed measurement, enabling 360 degree wind speed measurement with high accuracy. Due to the light weight and reduced friction, it can improve the sensitivity and ensure the accuracy of the measurement. It is characterized by low power consumption, stable performance and high efficiency. This design enables the wind speed detector to work stably for a long time. 2. Durable Material: The wind speed detector is made of ABS material, which is resistant to acid and alkali and other characteristics, greatly extending its service life. This design ensures the stability and durability of the wind speed detector in harsh environments. 3. Waterproof Cable And Anti Interference Ability: The wind speed detector is equipped with 8M waterproof cable, which is oil proof and has strong anti interference ability to ensure the stability of signal transmission. This makes the wind speed detector work normally in various environments. 4. Widely Used: Three cup wind speed detector is a special meteorological measurement tool. It can be widely used in power plant wind speed measurement, meteorological monitoring wind speed and wind direction measurement and so on. 5. Easy Installation: The three cup wind speed detector is easy to install with a 4cm mounting hole. This makes it easy for users to install it in the desired location, and it is simple to operate and easy to use.
