The MUYA GT8907 is a vane-type digital anemometer that measures wind speed, air volume, temperature, and humidity for HVAC, workshop, and general environmental monitoring. It captures current, average, maximum, and minimum airflow via an extendable rotating vane sensor, with readings expressed in CFM or CMM. A USB connection with companion software lets readings be logged and reviewed on a computer, and the unit runs on standard AAA batteries with auto shut-off.
