- Maintenance-free operation through ingenious technology without any moving parts
- Extremely fast measurement from the first raindrop
- Differentiation between eleven classifications of drop sizes
- Detection of precipitation and rainfall (rain, freezing rain, hail, snow and sleet)
Absolutely maintenance-free and extremely fast measurement of precipitation type (rain, snow, sleet, freezing rain, hail) and intensity, thanks to radar measurement technology. The smart radar rain sensor & present weather detector!
The Lufft WS100 is our rain sensor with radar technology and adjustable heating. Using a 24-GHz Doppler radar, it measures the speed of all forms of condensed water. These include rain, freezing rain, hail, snow and sleet.
The low-energy sensor detects precipitation from the first drop. Its possible uses are nearly unlimited. Whether in hydrology and water management, agricultural and environmental science, building automation, meteorology or airport and traffic control: the rain gauge measures rain almost anywhere in the world.
