The YOUNG Model 91000 ResponseONE™ Ultrasonic Anemometer measures wind speed and wind direction with no moving parts.  The IP66 rated construction enables reliable operation in severe environments.  Each sensor is fully wind tunnel tested and calibrated to provide accurate wind measurement over a wide operating range.  Standard serial output formats include SDI-12, NMEA, and ASCII text.  Output may be continuous or polled to conserve power.  Standard RS-232 or RS-485 serial formats enable direct integration with YOUNG displays, marine NMEA systems, data loggers or other compatible serial devices.  The sensor mounts on a standard 1-inch IPS pipe.  A mounting orientation ring is included that engages with the base of the sensor to retain orientation when the sensor is removed for maintenance.  Terminations are made in a junction box at the base of the sensor by small clamp-style connectors (no special connectors are required).

The YOUNG Model 91000B ResponseONE™ Ultrasonic Anemometer is black in construction.  All other features are identical to Model 91000.

The YOUNG Model 91500 ResponseONE™ Ultrasonic Anemometer includes an internal compass to provide orientation for wind direction, making it ideal for mobile or portable applications.

The YOUNG Model 91500B ResponseONE™ Ultrasonic Anemometer is black in construction.  All other features are identical to Model 91500.
