Vane Anemometer VA8020/VA8021/VA8022

Wind speed measurement series Anemometer is composed of the three instrument: Type A(Temperature/Vane anemometer)/Type B(Temperature/Humidity/Vane anemometer)/Type C(Temperature/Air volume/ Vane anemometer). This Anemometer is normally used to measure the wind speed and volume flow at ventilation outlets. In addition to the measurement of humidity and temperature, climatic conditions can also be analysed

    During use:

    To guarantee correct readings: position instrument so that flow impacts at the rear.
    Do not press the vane sensor.
    The vane sensor should aim at the wind direction.
    When performing the temperature and humidity measurenment, in order to ensure the accuracy of the measurement readings, all the interference sources which may affect the measurement results about temperature and humidity (such as the hand) must be away from the sensor.
