Abstract
Abstract A plurality of measuring probes are sequentially positioned in a conveyor tube in the vicinity of a measuring and evaluating device for determining the activity in each probe. The probes are moved in sequence by a control unit into operative proximity with the measuring and evaluating device. The control unit comprises an elastic wire in the tube blocking the probes and a moving device for controllably withdrawing the wire from the tube.
