R3-100 Research Anemometer
The R3-100 anemometer is 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 at environmental operating temperatures of -40ºC to +60ºC. 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.
