The R3-100 anemometer is ideal for scientific research applications, with a fast sampling rate of 100 Hz. 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 0-45 m/s (0-100 mph) at environmental operating temperatures of -40º C to +60º C. Analogue, sonic temperature, speed of sound and U,V,W vector outputs are provided as standard, with optional analogue and PRT inputs available.

The R3-100 offers class-leading 3-axis wind measurement in a robust aluminium/carbon fibre construction.
