Abstract
A particle counter for counting a number of particles in an air sample includes a sampling probe connected to a counter body with an intake section of the sampling probe having an adjustable area. The intake section is constructed of a plurality of telescopically interconnected shaped pieces that slide within one another to permit lengthening and shortening. The degree of lengthening or shortening determines the adjustable area of the sampling probe, which corresponds to an air speed of the air sample to provide precise particle measurements.
