WS Series

All-in-One measuring system for the measurement of wind speed, wind direction, temperature, relative humidity, barometric pressure, global radiation and precipitation

Depending on the particular model, the instruments in the WS series provide a low-power ultrasonic wind sensor incorporating an electronic compass for automatic adjustment for magnetic North, a NTC air temperature sensor, a capacitive sensor for air humidity, a sensor for barometric pressure, one for global radiation (CMP3) and a tipping bucket rain gauge for liquid precipitation. SDI-12 Output.
Thanks to a configurable low-power mode, the units are ideally suited for all solar-powered hydro-meteorological applications.
