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 ? 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.
