Met One MSO Weather Sensor

MSO Cup and Vane Weather Station

Compatible with the following Aeroqual products:
  • AQM 65 compact air quality station
  • Dust Sentry dust and particulate monitor
  • Dust Profiler dust and particulate counter

The Met One MSO delivers the following measurements all in one package:

  • Wind speed
  • Wind direction
  • Air temperature
  • Relative humidity (RH)
  • Barometric pressure


Wind Speed and Wind Direction are measured using conventional cup and vane techniques. All other measurements are housed in a multi-plate naturally aspirated radiation shield to reduce solar radiation errors.

The shield is constructed of a series of concentric white aluminum plates, which allow air to fl ow through the shield, while blocking direct solar rays.

The temperature sensor is a platinum RTD class 1/3B. Relative humidity is a based on our very accurate solid
state sensor designed for continuous exposure to adverse climates.

The barometric pressure sensor is a piezo-resistive device designed for robustness, high accuracy needs, as
well as long term stability.
