ULSA is an acronym derived from the UltraSonic Anemometer, an ultrasonic wind direction and speed meter.
ULSA is a technology born during the research and development of gliding recovery balloons in STRATOVISION. By purchasing ULSA, STRATOVISION can continue its journey towards the development of new balloon technologies.
ULSA M5B / BASIC is not waterproof. Please use it indoors or temporarily outdoors under clear weather conditions (avoid using it in outdoor applications during rainy weather).
Examples: drone mounting, indoor airflow measurement, etc.
There is a 1/4-20 UNC screw on the bottom surface. You can mount and install it using your camera tripod.
