Met One MSO

Multiparameter weather sensor

Part # 51127

met one mso weather station

The Met One MSO combines five of the most popular meteorological measurements into one simple, economical package, allowing for efficient, accurate and comprehensive weather monitoring to be added to any existing site or new installation.

The MSO features wind speed, wind direction, temperature, relative humidity, and barometric pressure sensors. A rainfall measurement option can be added by integrating a tipping bucket rain gage directly into the serial message being outputted by the MSO, or by simply connecting it to another port on a data logger shared with the MSO.

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 flow through the shield, while blocking direct solar rays.

The temperature sensor is a platinum RTD class 1/3B. Relative humidity is based on Met One's 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.

The pre-assembled MSO is ready for immediate deployment and includes u-bolt hardware for mounting to a pole, mast, or pipe. The air temperature, humidity, and barometric pressure sensors are housed in a solar radiation shield positioned below the mechanical wind direction and speed sensor.

What's the Easiest and Quickest Way to Start Collecting Data and Access it Anywhere?

The Answer's in the Cloud.

eTracker is a cellular modem and "virtual" cloud-based data logger in one (meaning you don't need to install a separate data logger). Simply connect your sensor and a power source to eTracker and you're done. Configure (or reconfigure) anytime from any Internet-connected device, and use Stevens-Connect to retrieve your data, or forward it to your favorite software system.
