Apparatus for determining physical characteristics of plant root samples.

摘要

An apparatus for testing a sample of fibres or filaments including a scanning zone (50) in which said sample is located and scanning means (52). Transport means is provided for producing relative movement between the scanning zone (50) and the scanning means (52) whereby to define a primary scan path therebetween. The scanning means includes irradiation means (9) arranged to irradiate a portion of the scanning zone, and at least one radiation detector (57) responsive to the irradation whereby to provide an output indicating the presence or otherwise of a discrete length of fibre or filament in the portion, and processing means for processing the detector output to provide a measure of one or more parameters of the sample.
