HS anemometer

Research quality 3-axis (3D) ultrasonic wind sensors

3D sonic anemometer for research, easy to use, suitable for field installation, available in two versions with 50 or 100 Hz update frequency.

The SIU unit provides 6 analogue inputs and 2 PT100 inputs with 14 bit resolution.

The PCIA unit allows connection to a PC and provides 4 analogue outputs.

The asymmetric head allows accurate measurement of vertical flow with minimal disturbance from the geometry of the anemometer.

It can easily be placed very close to the ground or near a crop or tree canopy to measure flow.

Ideal for eddy correlation measurements
