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.
