Ultrasonic Anemometer
Model 81000RE / Model 81000VRE
Both models have an extended mast that separates the transducer array from the instrument body. Each sensor is individually wind-tunnel calibrated. Wind and sonic temperature data is available on four voltage output channels (Model 81000RE). Serial RS-232 and RS-485 are available as well. The sensor installs on standard 1 inch pipe.
