DS2 Sonic Anemometer

Horizontal Wind Speed & Direction Measurement
The DS-2 Sonic Anemometer is a rugged, research-grade two-dimensional sonic anemometer built specifically for agricultural, forestry, and environmental research applications.

Accurate at Low Wind Speeds
A lower wind speed threshold of 0 m/s makes the DS-2 especially well-suited for measuring wind within plant canopies, where wind speeds are often below the threshold of a cup anemometer. And with a resolution of 0.01 m/s, the DS-2 is capable of recording fine-scale variations in wind speeds within and above plant canopies.

No Maintenance Required
The DS-2 is designed for long-term, maintenance-free operation. No moving parts means no mechanical wear and no need for oiling or replacing bearings.

Never Needs Calibration
The DS-2 uses ultrasonic sound waves to measure wind velocity and direction. Because this measurement comes from first principles, the DS-2 doesn’t ever need to be calibrated once it leaves the factory.

Uses Very Little Power
The DS-2 requires 100 to 1000 times less power than other ultrasonic anemometers.

Note: the DS-2 is also compatible with other data loggers. See specifications for more information.

Low Cost
Most agricultural and environmental researchers use wind as just one variable among many. Occasionally the scientific objectives of a study require multiple simultaneous measurements of wind to capture vertical or horizontal heterogeneity in the environment. A primary design goal of the DS-2 is to provide high accuracy wind speed and direction at a price that opens up research options, including greater spatial coverage.

Customized for Environmental Research
Wind speed and direction are fundamental measurements necessary for a wide range of agricultural, forestry, and micrometeorological applications. The DS-2 was designed to put the accuracy and low maintenance benefits of sonic anemometers in a sensor built specifically for these applications.

The DS-2 is not intended as a replacement for the high-end three dimensional sonic anemometers used by micrometeorologists. Itis designed to provide agricultural and environmental researchers a high accuracy, low maintenance solution for measuring horizontal wind speed and direction.

Output
The DS-2 reports wind speed and maximum gust speed in meters per second with a resolution of 0.01 m/s. It also reports wind direction with a resolution of 1 degree.

If the sampling rate is greater than 0.1 Hz, the anemometer reports the speed and direction at the time of sampling. If sampled less frequently, the anemometer samples every 10 seconds, averages the vector components of the wind, and records the maximum gust during the specified sampling period.
