AIO 2 Sonic Weather Sensor

The AIO 2 Sonic Weather Sensor 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 includes a built-in compass used for automatic magnetic north alignment of the wind sensor. The temperature and humidity elements are integrated into an IP65 sealed module with a quick disconnect for ease of calibration in the field. The pressure element is precisely calibrated, and temperature compensated for outstanding performance.

The AIO 2 will accept data from a tipping bucket rain gauge, a compatible solar radiation sensor, or both.

The AIO 2 is designed for surface meteorological applications where accuracy and reliability matter.
