The deposit collector consists of two PE HD collecting flasks (2 litres each) that are screwed together.

A protective filter is integrated in the screw joint.

The receiving surface of 100 cm² is en-sured by an acrylic glass intake ring.

Deposition is recorded at 1m above ground.

The collecting flasks are kept in a PVC standpipe (diam. 130 mm) with a bird-repelling ring at its free end.
