The sampler followed a route to, and a criss-cross through, the zone, keeping on the move, more or less continuously, without fol-lowing the same route twice. Wherever people were encountered, air was sampled for dust counts, using a konimeter, at the rate of roughly one konimeter spot per two persons, whether they were at work, resting or walking.

- Carl Zeiss Konimeter Analog Weather
A konimeter is an instrument for measuring the dust content of a sample of air. A measured volume of air is drawn through a jet, to impinge on a surface coated with a glycerin jelly. The dust adheres to the surface and the particles are counted under a microscope. A manual for the Zeiss konimeter may be downloaded below (12 pages):

Methods of Aerosol Measurement before the 1960s
2022-2-21 The term konimeter was used before the 1960s to designate the one-stage impactor. The first konimeter was constructed by Sir Robert Kotze in 1919 in the Union of South Africa. The dust particles were collected by impaction on a glass plate covered with a thin film of petroleum or glycerin jelly, which trapped and retained the dust.
