ABSTRACT:
A cord sampler for sampling impure granular materials a small hole in a wall of the hose connection between a pressure side of a blower and a simple tubular sampling spear, through which hole a weak air flow will be blown out, whereby a correspondingly weak air intake will occur through and open end of the spear, and hereby a considerable improvement of the sampling accuracy is obtained. A similar, but smaller hole may be provided in the suction connection to the spear in order to reduce a vacuum at this place.
