Sonic Weather Station
Features • Wind Speed and Direction • Temperature • Humidity • Barometric Pressure • Rain and Solar Radiation Options • Rugged all metal housing • SDI12, RS232, RS485 Outputs • Met One 7500 Protocol • Compact 10cm Diameter
The Sonic Weather Station (SWS) is a complete high
performance weather sensor using Met One Instruments’
proven 2D sonic technology. This technology provides
reference grade accuracy without moving parts and a builtin compass used for automatic alignment of the sensor.
The temperature and humidity elements are integrated
into an IP65 sealed module with a quick disconnect for
ease of calibration in the fi eld. The pressure element is
precisely calibrated and temperature compensated for
outstanding performance.
The SWS is designed for surface meteorological
applications where accuracy and reliability matter.
Options:
– 10600 USB and power interface.
– WMO compliant external tipping bucket rain gauge
connects simply and allows for correct installation and
siting per industry guidelines.
– Solar radiation sensors are connected easily and
integrate seamlessly into the SWS data record. Specifi cations
