The R. M. Young anemometer Model 81000 is an Ultrasonic Anemometer with a 3-axis, no-moving-parts wind sensor. It is ideal for applications requiring fast response, high resolution and three-dimensional wind measurement.

The ultrasonic wind speed sensor features durable corrosion-resistant construction with 3 opposing pairs of ultrasonic transducers supported by stainless steel members. Each 81000 RM Young Anemometer is individually wind-tunnel calibrated. Wind and sonic temperature data is available on four voltage output channels. Serial RS-232 and RS-485 outputs are available as well. The ultrasonic wind speed sensor installs on standard 1 inch pipe.
