Product description
The Rika Sensors RK900-10 is a high-precision automatic weather instrument that redefines environmental monitoring by eliminating mechanical wear. It uses ultrasonic principles to measure wind speed and direction, and 24G radar technology to instantly detect precipitation, even identifying the type of rain, snow, or hail.
This all-in-one station simultaneously measures temperature, humidity, atmospheric pressure, solar radiation, illuminance, and dust concentrations (PM2.5/PM10). Its compact design with IP66 protection and automatic heating makes it suitable for extreme climates. Thanks to its built-in GPS and electronic compass, it is the perfect solution for fixed or mobile stations on vehicles and vessels, accurately calculating true wind speed while moving.
