    An Automatic Dust Sampler based on the Konimeter

    This is a motor-driven konimeter which takes 30 separate dust samples at regular intervals, which can be varied from 4 to 60 minutes, giving total sampling times between 2 and 30 hours. The dust spots are arranged on the circumference of a glass plate. The apparatus is said to be an improvement on the recording konimeter made by Zeiss, Jena, which produces a continuous dust trace.
