A trapping and measuring device is provided for collecting and weighing wind borne particles of sand in the desert or the like. The device includes a rotatable trapping housing which is constructed to permit the wind to pass therethrough while trapping the sand carried by the wind. The column-like housing is mounted on a fixed base which contains a funnel and collector cup assembly together with a transducer for weighing the sand collected in the cup. A wind-catching plate attached to the rotatable housing provides orientation of the housing entrance openings so as to face the wind. A tortuous path provided within the trapping housing promotes release of the sand from the wind passing through the housing and screens at the exits block egress of the sand.
