  • Product Name: RK900-10 Ultrasonic Automatic Weather Instrument


RK900-10 automatic weather instrument is simultaneously measure the atmospheric temperature, atmospheric humidity,air pressure,wind speed, wind direction, solar radiation,Illuminance/UV,dust concentration and precipitation.Temperature, humidity and air pressure sensor is placed within the radiation shield.Wind speed and direction of ultrasonic principle.24G radar detection on rainfall, which can quickly detect rainfall and rainfall intensity.Internal GPS global positioning module and electronic compass can be mounted to the system to give a good indication of latitude and longitude and relative speed, which can calculate the real and virtual wind speed and direction, and is especially suitable for installation on motion vector, such as special vehicles or vessels, etc.

 FEATURES
