Sonic DA-700 Ultrasonic Anemometer Thermometer 3-D

SONIC’s Ultrasonic can measure 3-D Wind Velocity and Temperature in fast response. It can measurements of turbulent energy transport (heat and momentum flux) and Wind observations in the wind tunnels, buildings and on the bridges.
DA-700 also can flow monitoring in a clean room.


  • Digital processing using DSP provides high reliable data
  • Ultrasonic can measure minimum winds from 0m/s without moving parts
  • SONIC’s algorithm is not affected by temperature change
  • Lightning protection has been enhanced by selecting surge protective devices
  • Added operation of 3-sec/arbitrarily averaging and elevation angle calculation
  • Arbitrarily set-up data output of serial and 8ch analog signals
