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.
