Research R3-100_Mertani_Gill Instruments
3-Axis Ultrasonic Anemometer
The R3-100 (MTI.AWS.GL.R3-100 anemometer is Gill’s class-leading 3-axis anemometer ideal for scientific research applications, with a fast sampling rate of 100Hz. This 3-axis ultrasonic anemometer is used extensively for the determination of fluxes using the Eddy Covariance method.
R3-100 will monitor wind speeds of 0-45m/s, with analogue, sonic temperature, speed of sound and U, V, W vector outputs provided as standard and optional analogue and PRT inputs available. The R3-100 is of aluminium/carbon fibre construction and will operate effectively in environmental temperatures from -40°C to +60°C. Optional accessories are available such as cables, sensor input units (analogue inputs) and power supplies.
