Product Description

Hs-50 3-axis Horizontal-Head Research Anemometer

This instrument utilises advanced ultrasonic measurement technology, with a unique horizontal head design that allows for more accurate measurement of vertical flows with minimal interruption from the anemometer geometry. The head features a built-in inclinometer for simple positioning of the instrument on a tower or mast. A separate electronic unit allows easy access to the PRT and 6 analogue inputs.

HS-50 will monitor wind speeds of 0-45m/s, with a fast sampling rate of 50 Hz. The instrument can be positioned close to the ground or to crop and tree canopies for accurate measurement of surface turbulence.
