3-Axis Horizontal-Head Research Anemometer
Gill 3-axis Research range of ultrasonic anemometers offers users a number of different instruments. This range is valued for the quality of its measurements and is used by recognised experts to gather data they reply upon for their research and publications.
The Research range includes models featuring horizontal head configurations for highly accurate vertical flow analysis, with minimal interruption from anemometer geometry. These models have a built in inclinometer to assist set-up on towers or masts.
The HS-100 3-axis anemometer features a horizontal head design, which allows for accurate measurement of vertical flows with minimum flow interruption from the anemometer geometry.
Ideal for scientific research applications, HS-100 is capable of monitoring wind speeds of 0-45m/s and offers a fast update rate of 100Hz for precision wind analysis.
The head of the anemometer features a built-in inclinometer to allow the instrument to be accurately positioned on a tower or mast. Access to the PRT and analogue inputs is provided via a separate electronic enclosure. The instrument is ideal for analysis of surface turbulence and can be positioned close to the ground or crop and tree canopies.
