The Vevor portable split-design anemometer is a 4-in-1 meter that measures wind velocity, wind temperature, air flow, and wind chill. It features an LED backlit screen for clear readings in different lighting conditions and supports six wind speed units for flexible measurement. Its IP44 protection rating, excluding the vane unit, helps it perform in challenging outdoor conditions. The included 6.6' extendable cord, lanyard, and storage bag make it convenient to use and carry for sailing, surfing, flying, HVAC, and other applications.
