The indoor-outdoor psychrometer according to August is used to precisely measure air temperature and humidity.
It is designed for indoor and outdoor use.
To accurately determine relative humidity, a flow velocity of approximately 2 m/s is required. If the flow velocity is lower than this value, the measurement error increases.
