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 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 field. The pressure element is precisely calibrated and temperature compensated for outstanding performance.
The AIO 2 is designed for surface meteorological applications where accuracy and reliability matter.
Accessory Options:
- 10600 USB and power interface
- WeatherView software for real time weather display and data recording on a PC
- Universal mounting hardware
- 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 AIO 2 data record.
